Email Encryption Gateway release notes

This document lists the release notes of the CipherMail Email Encryption Gateway. Important changes to the ciphermail-core project are also listed here. Changes that only affect the professional/enterprise version are marked with '[PRO/ENT]'. Special changes for enterprise customers are marked with '[ENT]'.

The release dates shown here represent the dates the finished builds were made available through our distribution channels. There is often a delay between the source code releases (or tags) and the releases of the finished builds.

4.11.0 (2021-02-08)

New features

  • Add option to select if database and/or other files should be included with backup/restore.
  • JMS support added (activeMQ). The built-in CA generates an event when a new certificate is generated. PGPSecretKeyRequestor generates and event when a new PGP keyring is created.
  • Event handler for certificate generator event added which can be used to upload the certificate to an external LDAP database. [PRO/ENT]
  • Event handler for new PGP keyring event added which can be used to upload the PGP key to some remote system. [PRO/ENT]
  • Location and owner (group) of the postfix socketmap domain socket is now configurable. [PRO/ENT]

Technical changes

  • LDAP certificate lookup script refactored. Setting overrides can be configured in a defaults include file. Recipients can be excluded or included from a lookup. [PRO/ENT]
  • Enable the network interface (i.e., set ONBOOT to true) when the interface is configured (the offline installer starts with a disabled interface). [PRO/ENT]

4.10.0 (2020-11-19)

New features

  • PGP ECC support added. ECC keys can now be generated. The gateway can now use ECC keys for encryption and decryption.
  • PGP option "Auto select signing algorithm" added. This is enabled by default.

Technical changes

  • BC jars updated to 1.67.
  • start.sh removed. To start the back end locally for development, use the ant start-back task.
  • The EJBCA configuration has been moved to its own file (ejbca-certificate-request-handler.xml).
  • For unit testing and development, a Docker Compose file is added which starts PostgreSQL, MariaDB and SKS keyserver containers.
  • The back-end project is now called ciphermail-core. For backward compatibility, the Debian and RPM package names will not change.
  • The front-end project is now called ciphermail-gateway-web. For backward compatibility, the Debian and RPM package names will not change.
  • The jars from ciphermail-core are now used in multiple projects.
  • Templates are now sorted (with the exception of custom templates, which always come at the end).
  • Unbound and OpenLDAP Dockerfiles added for unit testing. [PRO/ENT]
  • Sun PKCS11 provider was changed from Java 8 to Java 11 in a non-backward compatible way. Because we never used the Sun PKCS#11 provider, we removed the code. [ENT]

Miscellaneous

  • Logo color changed to match new color scheme.
  • We have migrated all our Subversion repositories to Git. The source code of ciphermail-core and ciphermail-gateway-web are now mirrored on GitLab.com.

4.9.1 (2020-07-07)

New features

  • PGP "private key alias" and "key algorithm" added to PGP view.
  • The administrator can now override the default (root) target processor on the respool page.
  • The session timeout of the administrative web interface can be configured using the property ciphermail.gui.admin.max-inactive-interval.
  • Support for Luna HSM added [PRO/ENT].
  • PKCS#11 template attributes can be overridden from an XML file [PRO/ENT].

Technical changes

  • Java wrapper ./lib and ./lib.d added to library.path (this is for example needed for Luna HSN support)
  • If a PGP private key is not accessible, for example when an HSM is used and the key is not available, a warning icon is shown.
  • Logging improved for email sent from back-end which and is not accepted by Postfix (for example because the email is too large).
  • MTA "after queue filter size" and queue_min_free is now calculated based on the configured maximum message size.
  • MTA "before queue filter size" renamed to "Message size limit" and "after queue filter size" removed from administrative web interface.
  • HSM watchdog now checks if the key store is the CipherMail Database KeyStore and if so, exits [PRO/ENT].
  • NTA 7516 code refactored and updated to match latest specifications [PRO/ENT].
  • Default Postfix setting change: smtp_address_preference is now set to 'ipv4'.
  • X-Forward-For header is now by default removed unless the IP address comes from a trusted proxy (see /etc/httpd/conf.d/x-forward-for.xml) [PRO/ENT].

4.9.0 (N/A)

Version 4.9.0 was an internal release.

4.8.0 (2020-05-27)

SECURITY fixes

  • Fix for privilege escalation issue (CVE-2020-12713).
  • Fix for weak Diffie-Hellman parameters (CVE-2020-12714).

A patch script for both vulnerabilities is available for users of older Email Encryption Gateway versions.

New features

  • Support for Securosys HSM added. [ENT]
  • ECallSMSTransport2 added which supports the new eCall API. [PRO/ENT]

Technical changes

  • Java 8 or up is now required.
  • Apache CXF jars and dependencies updated from 3.0.12 to 3.3.6.
  • hsm-iaik-watchdog.xml renamed to hsm-watchdog.xml. [ENT]
  • Docker Compose file added for unit testing.

Bug fixes

  • Certbot timer was not started. [PRO/ENT]

4.7.1 (2020-01-22)

New features

  • Wizard added for requesting ACME (Let's Encrypt) certificates for use with the virtual appliance. [PRO/ENT]
  • Wizard added for importing trusted system root certificates. [PRO/ENT]

Technical changes

  • SMTP connection throttling and maximum queue size changed (to 1000) to limit the number of emails in the spool queue. We want queuing to be done by Postfix.
  • IsDatabaseInactive matcher added which checks if the database is active. The matcher is called just before a message is delivered back to Postfix. If the database is not active, the message will be stored in the error spool. This is to prevent email from being sent unencrypted when the database is not functional.

Bug fixes

  • Only scan for attached S/MIME attachments (AttachedSMIMEHandler) if the part is a multipart message or if the filename is smime.p7m, smime.p7s or smime.p7z. This fixes a bug where a signed PDF was incorrectly identified as being an S/MIME blob.

4.7.0 (N/A)

Version 4.7.0 was an internal release.

4.6.2 (2019-12-23)

New features

  • Support added for the Dutch NTA7516 draft standard (VWS-project Veilige Mail). [PRO/ENT]
  • Logos modifiable by the administrator are now stored in a logo registry. A standard logo editor can be used to add additional editable system logos. [PRO/ENT]
  • System sender and From addresses can now be specified. These addresses are used by some system-generated notification messages. The default system sender is the null sender. The default From address is 'postmaster'. The default email templates have been modified to reflect this change; From is set to 'postmaster' if not overridden.
  • The MPA log viewer now supports multiple log files. Previously only the last two MPA log files were shown. The administrator can now select the number of log files to show and filter on.
  • The system URLs (Base URL, OTP URL etc.) can now be set on domain and user level. Previously this was only possible on the global system level.
  • Subject and header triggers added for skipping encryption, forcing the use of Webmail Messenger and forcing encrypted PDF messaging. [PRO/ENT]
  • It is now possible to prevent the Gateway from adding certain security keywords by setting the related subject tag to "\<skip>".
  • Command line script added for adding log statements to the MPA log.
  • The CertStore command line tool was updated: certificates can now be validated, output can be written to a CSV file.

Technical changes

  • Native NTLM client support is now disabled because only version 1 was supported, which is insecure and discouraged by Microsoft. If you need NTLMv2 support, use the included cntlm proxy or an NTLM proxy of your choice.
  • Notify and PDFEncrypt "userProperty" must now be a JSON string. If you have modified the standard config.xml file, or any other MPA XML fragment that uses Notify or PDFEncrypt and where "userProperty" is set, please update these XML files to make sure that the new JSON configuration is used.
  • System jars updated for Java 11.
  • The type of the cm_value field of the cm_properties_cm_name_values table was changed to mediumtext in order to support larger values. This change only affects installations that use a MariaDB or MySQL DBMS.
  • Subject encryption triggers are now removed from incoming messages before the S/MIME handler is executed. We need this so we can trigger on the "decryption info tag" when a reply to an email is sent so we can force encryption if the email was received by the Gateway in encrypted form.
  • The maximum MPA log size is now 20MB (was 10MB). The log is rotated once it reaches this size.
  • Packages are signed with a new signing key. The fingerprint of this key is 034416869EBF877A9C37B22E81DD361DC65A8999.
  • dnsjava upgraded to 2.1.9.
  • All non-CipherMail package dependencies for the RPM and Debian packages are removed. This makes it easier for us to support multiple RedHat/CentOS and Debian/Ubuntu releases.
  • Parts of properties code changed to improve multitenancy.

Bug fixes

  • Email address highlighting was missing the '-' character in domain names.

Miscellaneous

  • The 'Reporting' menu item was moved to the 'Other' pull-down menu. [PRO/ENT]
  • The 'Logos' menu item was moved to a new 'Style' pull-down menu. [PRO/ENT]
  • Subject and header trigger settings are now moved to dedicated pages. This allows us to support multiple triggers without cluttering the settings page too much. The triggers can be accessed from the new 'Triggers' pull-down menu on the 'User', 'Domain' and 'Global settings' pages.

4.6.0 - 4.6.1 (N/A)

Versions 4.6.0 and 4.6.1 were internal releases.

4.5.0 (2019-09-12)

New features

  • Support for Securosys Primus HSM added. [ENT]
  • Intellicard Certificate Request handler added. Certificates can now be automatically requested from the Intellicard remote PKI. [PRO/ENT]
  • There is now a help button for most pages and settings. If clicked, the online help page for that page/setting will be opened.
  • Additional email forwarding rules can be configured. [PRO/ENT]
  • Wizards added for initial setup, encryption setup and importing TLS certificates. The wizards make it easier to set up and configure the Gateway. [PRO/ENT]
  • GetPasswords mailet added.
  • PDF option 'Use reply sender' added. If 'Use reply sender' and 'Reply sender' are set, the 'Reply sender' email address is used as the sender of the PDF reply email.
  • DKIM sign/verify now supports different cryptographic providers. This is required for HSM support.
  • Every admin page now contains the admin menu. If you open an admin page, you no longer have to use the back button to open another one.
  • JEVAL decryptString function added. EvaluateUserProperty matcher now supports decryptString function.
  • Freemarker DecryptString method added (which cannot be used from a freemarker template).
  • PGP 'Ignore parsing errors' checkbox added. If set, only the faulty key from a keyring is skipped, the other keys are still imported.

Technical changes

  • Postfix main setting daemon_directory was changed for SUSE (/usr/lib/postfix -> /usr/lib/postfix/bin).
  • Domain validator is now more strict. A domain fragment cannot start or end with a dot or contain consecutive dots.
  • Additional HTTP security headers (Content-Security-Policy, X-XSS-Protection, X-Content-Type-Options, Referrer-Policy, Feature-Policy) added to Apache HTTP Server configuration. [PRO/ENT]
  • DNS and network settings are now always reconfigured in the background when restarted from the administrative web interface.
  • For most RPM spec configuration files, '%config(noreplace)' is replaced by '%config'.
  • Improved parsing of 'unparseable' PGP keys.
  • A PDF reply message will now contain the 'X-CipherMail-Reply' header.
  • Dynamic memory allocation is no longer calculated in the default include file but in the startup script. The maximum amount of memory available to the application can now be overruled with the /etc/default/djigzo-override file. We need to set a higher limit for the virtual appliance because it runs on 64-bit Linux, which has a much higher memory ceiling.

Bug fixes

  • The TLS/SSL import page now allows an empty password.

Miscellaneous

  • Network, software and system update layouts now use tabs instead of links.
  • Fixed sonarlint warnings.
  • Some pulldown menu items (Settings/Other, Admin/Other and MTA) are now sorted.

4.4.0 (N/A)

Version 4.4.0 was an internal release.

4.3.0 (2019-01-30)

New features

  • The IP address range used by Office 365 and G Suite can be automatically configured. This makes it easier to use the Gateway with these services. [PRO/ENT]
  • MTA lookup tables can be configured from the administrative web interface. This allows you to configure your own MTA maps, for example to configure a fine-grained TLS policy. [PRO/ENT]
  • Front end rework. The Bootstrap HTML/CSS framework is now used for the web interface. The interface is now responsive and scales on mobile devices. Some menu items are combined under one pulldown menu (like the S/MIME menu), while others have been moved.
  • MimeEncodeHeaderMethod freemarker method added. This can be used for UTF-7 header encoding.
  • EncodedSubject template parameter added. This parameter contains the UTF-7 encoded subject.
  • Metrics added for data leak prevention and encryption failures. [PRO/ENT]
  • The 'Download key' page now supports downloading PEM-formatted keys.
  • The web server can now be restarted from the 'System' page.
  • License notifications added. A notification is sent if 25%, 50%, 75% and 100% of the max licenses have been assigned. A license expiration warning is shown if the license is about to expire in 30 days. A daily notification is sent if the license expires within 7 days. [PRO/ENT]

Technical changes

  • Factory property files are now read from conf/djigzo.properties.d in sorted order. This can be used to add new factory properties or to override existing properties.
  • The virtual appliance no longer maximizes the back-end memory to 2 GB. This limit was due to the 32-bits Linux not supporting more than 2 GB for the Java virtual machine.
  • GlobalSign certificate request handler added. S/MIME certificates can now be automatically requested from the GlobalSign Managed ePKI service. [PRO/ENT]
  • Changes to the LDAP configuration. The LDAP server URL and credentials should now be configured in ldap-context-source.xml. [PRO/ENT]
  • Milter classes refactored. The "Change sender" milter has been added. [PRO/ENT]
  • Postfix long queue IDs are now enabled by default.
  • New TLS certificates for the web server are now installed using a Bash script. This requires that the Tomcat -Ddjigzo.home parameter is set.
  • Reboots and shutdowns are now done in the background to prevent browser errors.
  • Post-quarantine processors renamed. There are now special processors used for email released from quarantine.
  • MariaDB JDBC driver updated to 1.7.4.
  • Apache HTTP Server is now used for the front end of the professional/enterprise virtual appliance. Reconfiguring the web server for new TLS certificates is now much faster and does not invalidate existing sessions. Another benefit is that Apache HTTP Server allows for a large number of configuration options, ranging from custom headers to specific TLS settings. [PRO/ENT]

Miscellaneous

  • General housekeeping of copyright statements, expired test keys/certs, code etc.

4.2.0 (N/A)

Version 4.2.0 was an internal release.

4.1.3 (2018-08-14)

New features

  • Support for Clickatell connect SMS API added.

Bug fixes

  • Attachments could not be added to the PDF reply because of the 'X-Frame-Options' header, which was added in version 4.1.2. The header value is now set to SAMEORIGIN instead of DENY. Ref: GATEWAY-115.

4.1.2 (2018-06-07)

New features

  • EFAIL detection added.
  • MTA lookup tables can now be configured from the administrative web interface. This allows you to easily configure your own MTA maps, for example to enforce a strict TLS policy for certain domains. [PRO/ENT]

Technical changes

  • TLSv1 and TLSv1.1 have been disabled in the web server, only TLSv1.2 connections are now supported.
  • Clickjacking protection with the 'X-Frame-Options' header added.

4.1.1 (N/A)

Version 4.1.1 was an internal release.

4.1.0 (2018-05-08)

New features

  • The CertStore command line tool can now export certificates and keys.
  • The PGP command line tool can now export (public and private) keys.
  • The back end now supports a mail attribute named 'remote-delivery.smtp.relay-host'. It can be used to deliver mail to a different relay host or local service based on the message content.
  • SetRecipients mailet added. This can be used to change the recipients of a message.
  • Matcher added for matching on a user-configurable list of senders and recipients. This also works for Exchange's journaling messages by looking inside the journal. [PRO/ENT]
  • Intellicard certificate request handler added. [PRO/ENT]
  • The database can now be exported in XML format. [PRO/ENT]
  • The hardware security module integration now supports the RSAES-OAEP encryption scheme, which is a requirement for the German edi@energy standard. [PRO/ENT]

Technical changes

  • The post-processors for S/MIME and PGP are now only called when a message was encrypted with S/MIME or PGP. The post-processor functionality can be used to tweak the behavior of the Gateway when a message is decrypted. One example might be to redirect the decrypted message to a content scanner for virus or spam filtering.
  • Systemd unit 'fetchmail.service' added.
  • SleepTimeOnError added to SMSGatewayImpl background thread. The thread will sleep for 30 seconds (configurable) if there was an exception in the background thread not caused by a transport. This is done to prevent overwhelming the system with log messages if there is a problem with the database.
  • S/MIME command line tool refactored. The tool now uses long option names.
  • System property ciphermail.crypto.cms.mustProduceEncodableUnwrappedKey added. This sets the mustProduceEncodableUnwrappedKey property for Bouncy Castle, which is needed for supporting hardware security modules produced by Utimaco.
  • Postgres JDB driver updated to support Postgres 10.
  • Most dependencies have been removed from the Debian and Red Hat packages. This makes it easier for us to support different Debian and Red Hat/CentOS releases.
  • The CipherMail Gateway virtual appliance is now based on CentOS 7 instead of Ubuntu and runs MariaDB instead of PostgreSQL. Unfortunately this means that backups of previous virtual appliances cannot be imported directly in CipherMail Gateway 4.1.0+. Users with a support contract can contact us for help with migrating the database to the new version. Note: this change only impacts customers who wish to upgrade to the new CentOS-based virtual appliance.
  • Jetty upgraded to release 9.4. This requires Java 8 or up. [PRO/ENT]
  • The selected certificate request handler is now session-persistent, which means that the selection is remembered while the session is active.

Bug fixes

  • Cipher suites for HTTPClient are no longer set. The cipher suite configuration resulted in a bug after a Java update. This only affects old versions of CipherMail Gateway that used a symbolic link to sunjce_provider.jar in /usr/share/djigzo/james-2.3.1/lib.
  • The varchar columns in MySQL/MariaDB databases have changed from a maximum of 128 characters to 255, because the 'alias' field was too short to fit a SHA-512 key thumbprint and related metadata. This resulted in a 'field too small' error when trying to set the key alias. [PROF/ENT]
  • SOAP communication between the front and back ends now uses HTTP Basic Authentication instead of Web Services Security to work around a recently introduced bug in Java 1.8.0_162. Ref: 1, 2
  • The CipherMail Gateway license was only checked during startup. [PRO/ENT]
  • Postgres 10 does not allow the JDBC URL to end with a slash character. The last slash has been removed from the URL.

4.0.0 (N/A)

Version 4.0.0 was an internal release.

3.3.1 (2017-10-08)

New features

  • S/MIME support for the RSASSA-PSS signing algorithm and RSAES-OAEP encryption scheme added. This is a requirement for the German edi@energy standard.
  • RPM packages can now be relocated.
  • PGPSkipSignOnly property added.
  • Authentication with Active Directory implemented for the administrative web interface. [PRO/ENT]
  • MPA log search filter now has a "context" option. If the context is set, context number of log lines before and after the match will be shown. This makes it easier to search for multi-line log output.
  • SMTP transport config is now directly editable from the GUI [PRO/ENT]
  • SMTP transport now allows mapping from email address to relay [PRO/ENT]

Technical changes

  • Bouncy Castle updated to 1.58. Note: the updated Bouncy Castle jar now strictly follows the standards for ASN1 integer encoding. Because of this some old, incorrectly encoded certificates might now be considered invalid. To revert to the old, less strict encoding, set the Java system property org.bouncycastle.asn1.allow_unsafe_integer to 'true'.
  • Freemarker updated.

Bug fixes

  • Trying to export a PGP secret key resulted in a NullPointerException if the selected keyring did not contain a private key.
  • The DHCP client used by the virtual appliance was not stopped when changing from DHCP to static network configuration.

3.3.0 (N/A)

Version 3.3.0 was an internal release.

3.2.7 (2017-04-24)

New features

  • IsSMIMEDeepScan matcher added. The IsSMIMEDeepScan matcher can be used to detect if a message is secured with S/MIME and if it contains an S/MIME attached message part (message/rfc822).
  • The Gateway now adds a special header to a message if the message could not be decrypted with S/MIME or PGP.
  • CertStore command line tool added for managing the certificate store. This replaces the old CertManager tool.
  • SMTPSink command line tool added for testing incoming email.
  • CheckKeyStore command line tool added for checking whether keys are accessible. This is currently used to validate key storage in hardware security modules, which is an enterprise feature.
  • conf/spring/spring.properties.d directory added from which properties files are read. This allows you to use '${...}' placeholders in Spring XML configuration files, which will be replaced by the values defined in the properties files.
  • REST service API added. [PRO/ENT]
  • Respool option added. This can for example be used to retry decrypting a message which could not be decrypted because the private key was not available when the message was received. [PRO/ENT]
  • Meta certificate request resolver added for trying multiple certificate request resolvers in succession until one returns a valid Distinguished Name for the certificate request. [PRO/ENT]
  • Static certificate request resolver added. This allows you to specify a static mapping from domain or email address to Distinguished Name parameters. [PRO/ENT]
  • Milter added for checking the MTA queue size and returning temporary errors (450) if the MTA queue size exceeds the limit. This can for example be used in a clustered setup to refuse incoming connections to a server under heavy load. [PRO/ENT]
  • Thales nCipher hardware security modules can now be used in high-availability clusters. The HSM keys are replicated between cluster nodes. [PRO/ENT]
  • On-demand key store added. This key store can be integrated with other security products or custom scripts to retrieve decryption keys from external systems on demand. [PRO/ENT]
  • A 'do nothing' post-smime-incoming processor added. This can be used to dynamically add new mail rules without having to change the XML configuration.
  • Support for SUSE Linux Enterprise Server 12 added.

Technical changes

  • Every CRL is now imported in a separate transaction instead of one transaction containing all new CRLs. This improves memory usage and makes it less likely that the transaction is rolled back in a highly-available cluster when the CRL was already imported on another node.
  • Added command line tool functionality for managing users.
  • Some Java libraries were updated.
  • system.trustAnchorBuilder.updateCheckInterval changed from 30 to 5 minutes. This is useful in highly-available clusters to make sure that the cached list of root certificates is somewhat synchronous.
  • Because some NIO classes are now used, Java 7 or up is now required.

Bug fixes

  • PDF encryption now supports deep scanning, which scans all (nested) MIME parts for attachments. This is needed because some clients (e.g. Apple Mail) put attachments inside text/html multipart-alternatives, which were not scanned when a text/plain version was available. Ref: GATEWAY-89.
  • PostgreSQL clauses NOCREATEUSER and NOCREATEDB are no longer used in the installation scripts. NOCREATEUSER is no longer supported in PostgreSQL 9.6. Ref: GATEWAY-108.

3.2.4 - 3.2.6 (N/A)

Versions 3.2.4 through 3.2.6 were internal releases.

3.2.3 (2016-12-12)

New features

  • Outgoing email can now be signed with DKIM. The signing keys can be configured for all mail, for mail from specific domains or for mail from specific addresses.
  • DKIM signing keys can be generated and stored on a hardware security module. [ENT]
  • Actions regarding data leak prevention (DLP) can now be delayed until it is determined whether a message was encrypted or not. This allows configuration of a DLP rule which is only activated when the message was not encrypted by the sender.
  • DLP validators added. A validator can check whether a matched pattern has some structure, other than those that can be matched with regular expressions. A credit card number for example can be matched this way, because credit card numbers use the Luhn algorithm. The currently supported validators can match Dutch citizenship numbers (BSN), U.S. DEA registration numbers, U.S. National Provider Identifiers (NPI) and arbitrary numbers that can be validated against the Luhn algorithm. [ENT]
  • Twilio and eCall SMS transports added. [ENT]
  • LDAP certificate lookup module added. The certificate lookup/download process can be modified by editing the default Bash script. [ENT]
  • The administrative web interface now has a page that displays the database cluster status. [ENT]
  • SMTP transport configuration page now supports specifying alternative TCP port numbers. [ENT]
  • Tool added for making and restoring backups to/from XML. This allows the Gateway configuration to be migrated to a different database type (e.g. from PostgreSQL to MariaDB). [ENT]

Technical changes

  • Phone numbers are now validated with libphonenumber.
  • The backup and restore functionality can now omit the database (i.e., only backup or restore configuration files).
  • Thread pool size for Apache CXF is now set to 10 threads instead of the default 200.
  • Java wrapper overrides should now be done in wrapper-additional-parameters.conf.

Bug fixes

  • Fixed hostname resolving issue. If the hostname was changed and the old hostname was no longer resolvable, it could happen that the front end was no longer able to connect to the back end, which would require a restart of the back end in order to restore service. Ref: GATEWAY-105.
  • Other minor bug fixes.

3.2.0 - 3.2.2 (N/A)

Versions 3.2.0 through 3.2.2 were internal releases.

3.1.2 (2016-08-23)

New features

  • dateCreated user property added.
  • Templates for OTP-encrypted PDF now include the password length in the filename of the PDF document.
  • Placeholder 'auto-submitted-incoming-verified', 'auto-submitted-incoming-invalid-signature' and 'otp-setup' processors added which can be overridden by optional Gateway modules.
  • OTP-encrypted PDFs are now supported in combination with the Webmail Messenger. [ENT]
  • The 'Reporting' page now reads supported parameters from a configuration file and dynamically updates the administrative web interface. [ENT]

3.1.1 (2016-06-30)

Technical changes

  • MySQL/MariaDB jdbc drivers updated.
  • Apache CXF upgraded. CXF now uses netty for SOAP server connections instead of jetty.
  • config.xml refactored. It is now easier to change the mail flow using additional XML fragments.
  • Advanced PGP option 'Skip non-PGP extensions' added. If enabled (the default), only attachments with the extensions ".pgp", ".asc", ".gpg" or ".sig" are scanned for binary PGP data. This should speed up the scanning of incoming messages.

Bug fixes

  • Fixed an issue where new admin roles could no longer be assigned or removed. Ref: GATEWAY-102.
  • The Enigmail PGP encryption add-on for Thunderbird shortens long filenames in a way that the JavaMail component of CipherMail Gateway could not correctly process. We have implemented a workaround for this.

3.1.0 (N/A)

Version 3.1.0 was an internal release.

3.0.5 (2016-04-18)

New features

  • Support for MySQL/MariaDB and Oracle Database added.
  • JDB connection tester tool added. This can be used to test a connection to an external database (PostgreSQL, MySQL/MariaDB and Oracle Database).
  • Log export functionality added to the virtual appliance. This used to be an enterprise-only feature.
  • Java 8 is now supported. Note: because elliptic curve ciphers are currently not supported for TLS in the RedHat/CentOS OpenJDK 8 packages, we recommend that users of these packages wait before upgrading.
  • The certificate request page now supports more request parameters, like country, locality, state and organizational unit.
  • The Gateway can now trim off whitespace at the beginning and end of all PGP header lines. Note that this is not enabled by default as this is not RFC compliant, and a system property must be set to enable it. Ref: GATEWAY-91.
  • PKCS10CertificateRequestHandler added for requesting S/MIME certificates from external certificate authorities. [ENT]
  • Additional SMTP configuration pages added: RBL, forwards, header checks and SMTP transports. [ENT]
  • SMTP SSL/TLS certificate management page added. [ENT]
  • System status page added. This page shows various graphs that can be used to get a quick overview of the state of the system. [ENT]
  • Logo module added, which can be used to change the logo displayed on the login and dashboard pages. [ENT]
  • Statistics module added. This module keeps track of the number of cryptographic operations per time unit. A PDF report with these statistics can be exported. [ENT]
  • Option added to webmail settings page for requesting read-receipts. [ENT]
  • License module added. [ENT]
  • TLS certificate signing request (CSR) module added. Requesting a TLS certificate signed by external CA can now be done from the administrative web interface. [ENT]
  • Webmail option 'only encrypt if mandatory' added. [ENT]
  • Update check added. [ENT]
  • Software install module added. This can be used to install new software using digitally signed software update packages. [ENT]
  • Support added for hardware security modules. [ENT]
  • Additional PDF features added: cover page, automatic renaming based on the attachment type, support for additional fonts, and configurable size limits of PDF attachments. [ENT]
  • Support for CipherMail Webmail Messenger added. [ENT]
  • LDAP mail rules module added. This feature can be used to change the mail flow based on LDAP object attributes. [ENT]
  • LDAP certificate request resolver added. When a certificate is requested, additional certificate request parameters (for example the common name, city and organization) can be obtained from the LDAP database. [ENT]
  • Email-based certificate request module added. If enabled, this module will automatically reply with a digitally signed email containing the S/MIME certificate. This can be used by an external user to retrieve the certificate, so that they can start an encrypted conversation. [ENT]
  • Remote system monitor added which can be used to monitor system variables. Scripts for monitoring with Icinga and Nagios are included. Examples of the variables that can be monitored are the size of the mail queues and the number of stored certificates. [ENT]
  • Notifications module added. If enabled, system notifications are sent to the configured recipients. An example of an action that may trigger a notification is when the Gateway imports a new certificate or PGP key from an incoming message. [ENT]
  • PEM to PFX conversion module added. This can be used to convert PEM files to password-protected PFX files. [ENT]
  • rsyslog module added. Logs from the mail processing agent and webserver will be sent to the rsyslog service. [ENT]

Technical changes

  • Because support for MySQL/MariaDB and Oracle Database was added, there is now a separate package for PostgreSQL. The main back end package no longer depends on the PostgreSQL package.
  • Mail generated by the administrative web interface is now sent to a local mail service on TCP port 10027. This makes it possible to change settings on the default smtpd port (25) without interfering with email sent from the administrative web interface. This requires an additional service setting for port 10027 in the master.cf file.
  • Libraries updated.
  • The database connection string is now stored in a separate XML fragment (hibernate.connection.xml). This makes upgrading easier because upgrading the hibernate configuration file no longer results in overwriting the database connection string.
  • ciphermail.backup.enabled system property added which can be used to disable the backup option from the administrative web interface.
  • The Tomcat servlet engine now only offers strong TLS ciphers to its clients.
  • Certificate/key import pages and PGP keyring import page now redirect the user to the parent page after import. The import result is shown in the parent page.
  • The default S/MIME encryption algorithm was changed from 3DES to AES-128, and the default signing algorithm was changed from SHA-1 to SHA-256. Since Windows XP is no longer supported, the stronger AES-128 and SHA-256 algorithms are now supported by most (if not all) systems.
  • The MTA page no longer has any advanced options since the old advanced options were actually important enough to be made visible at all times. The mailbox size limit is no longer editable by default since this is not used with a standard Gateway setup.
  • User objects are no longer created by default when certificates are created or requested through the CA module. This is now only done in case an inherited setting needs to be overruled.
  • The 'CA Request' page now supports downloading of certificate signing requests and uploading of certificates. This is not supported by all certificate request handlers.

Bug fixes

  • Java wrapper updated to 3.5.28. This fixes the following Java wrapper bugs: multi-byte character logging sometimes resulted in erroneous '?' in the log files, and a memory leak on RedHat/CentOS.
  • PDF encryption failed on non-standard Unicode characters (Webdings font). Ref: GATEWAY-92.
  • The PGP keyring importer did not report failure if the password was incorrect. Ref: GATEWAY-96.
  • Signing a message with PGP/MIME using an invalid content-transfer-encoding resulted in the message ending up in the error queue. Ref: GATEWAY-97.
  • The CA issue page now only complains of a missing CA if the built-in certificate request handler is selected.
  • The PGPKeyServer page now shows a scrollbar instead of letting long lines overflow.

Miscellaneous

  • The administrative web interface and user portal are now responsive (i.e., they scale on smaller devices).
  • Most close/cancel buttons were removed to make the administrative web interface more consistent. Users should use the back button or menu items for navigation.
  • The X500 subject field now shows most settings by default and only organizational unit under the 'more' option.
  • The order of items in the CA menu was changed. The CA settings page is renamed to 'Configure CA'.

3.0.0 - 3.0.4 (N/A)

Versions 3.0.0 through 3.0.4 were internal releases.

2.10.0 (2015-03-30)

New features

  • HTML parts are now scanned for PGP content. Ref: GATEWAY-88.
  • PGP desktop/universal (now Symantec) proprietary partitioned encoding format is now fully supported for incoming email. Email encrypted with PGP desktop/universal using the partitioned encoding format is now "repaired" to a proper MIME message.
  • RedHat/CentOS 7 is now supported.

Technical changes

  • The Gateway now ignores content-transfer-encoding of multipart messages.
  • The S/MIME handler now adds X-Djigzo-Info-Signer-Email-* headers with the email address on the signing certificate.
  • There is no longer a separate virtual appliance for VMware Workstation. The VMware virtual appliance now supports ESX 4+ and VMware Workstation 7+.

2.9.0 (2014-09-24)

New features

  • Global "Skip calendar messages" property added which will skip encrypting and signing if the message is a meeting invite. This is useful in case the invite recipient uses Outlook, as Outlook cannot handle encrypted or signed meeting invites.
  • PGP sign-only is now supported. "Only sign when encrypt" now also works for PGP messages. S/MIME signing is tried before PGP signing, i.e., if a sender has a valid S/MIME signing key, the message will be S/MIME signed. If the sender does not have a valid S/MIME signing key but has a valid PGP signing key, the message will be PGP signed. Signing of PDF encrypted mail now also supports PGP signing if a valid PGP signing key is available.
  • The Gateway administrator can now disable automatic PGP decryption. Doing so requires a change to the config.xml file. Ref: GATEWAY-81.

Technical changes

  • Symantec's PGP Universal Gateway uses non standard encoding for PGP/MIME. The header 'x-pgp-encoding-format' is now used to detect PGP/MIME encoding for messages generated by this product. Ref: GATEWAY-83.
  • The PDF encryption module now supports UTF-8 encoded passwords. Ref: GATEWAY-82.
  • The default signature algorithm for newly generated certificates is now SHA-256 instead of SHA-1.
  • BlackBerry module handling is no longer enabled by default. The module only supports BlackBerry OS 7 and lower using BlackBerry Internet Service (BIS). BlackBerry OS 10 does not use BIS, so for BlackBerry OS 10 the module is not required.
  • PGP/MIME encrypted messages now use 'inline' as default disposition. This is similar to how Enigmail sets the disposition and allows the Mailvelope browser add-on to open PGP/MIME encrypted messages.
  • Bouncy Castle library updated to 1.51.
  • Spring libraries updated to 3.2.9.
  • Spring security libraries updated to 3.2.5.
  • Incorrect web interface logins are now remembered for 5 minutes (was 1 minute).

Bug fixes

  • Startup failed if the Linux 'free' command was localized. A fallback to reading out /proc/meminfo is added which will be used if 'free' does not return the required data. Ref: GATEWAY-80.
  • PGP/MIME signatures were invalid if a multipart message contained extra newlines at the end of the message. The Zimbra mail client for example adds additional empty lines at the end of a multipart message. These lines are now removed before signing.
  • The NTP settings of the virtual appliance could not be changed. This was due to Ubuntu 14.04 using a different name for NTP server settings. Ref: GATEWAY-79.
  • Due to an incompatible change in a recent update of OpenJDK, CipherMail would no longer start up. Ref: GATEWAY-78.
  • PGP signatures are now created in plain text and not as a binary blob. This is a workaround for a bug in Enigmail 1.7.

Miscellaneous

  • The 'Mobile settings' link in the administrative web interface is disabled by default since the BlackBerry add-on is no longer enabled by default.
  • Minor changes to the 'Settings' page. Some settings were moved to additional settings and vice versa. Some settings were grouped differently.

2.8.6 (2014-06-10)

New features

  • OpenPGP support.
  • Support for SUSE Linux Enterprise Server.
  • A PDF reply now sets the In-Reply-To header. Conversation threading is now supported, i.e., the email client can now group the original message and the reply.
  • A comment field has been added to the user, domain and global properties.
  • MPA logging improved. More information is provided as to why messages are handled in a certain way.
  • The certificates filter in the administrative web interface can now filter on "expired only".
  • Fail2ban is now installed on the virtual appliance to provide better protection against brute force SSH login attempts.

Technical changes

  • The TCP port used by the SOAP back end changed from 9000 to 9009 to prevent a conflict with nCipher netHSM.
  • The default maximum message size for S/MIME and PDF is now set to 50 MB.
  • PDF encrypted email now uses the same Message-Id as the original message.
  • Lots of internal changes to allow new functionality to be dynamically added as plugins.
  • Session timeout of administrative web interface changed to 15 minutes and timeout of user portal changed to 30 minutes.
  • The virtual appliance has been upgraded from 32-bit Ubuntu 12.04 to 64-bit Ubuntu 14.04.
  • The default credentials of the administrative Unix user of the virtual appliance are now: username: sa password: sa

Bug fixes

  • Recent versions of OpenJDK register additional DataHandlers which can conflict with the way the back-end handles certain attachments. The additional DataHandlers are now ignored.
  • The fallback charset providers were accidentally disabled. They are now enabled again.

Miscellaneous

  • The software product has been renamed to CipherMail Email Encryption Gateway. The company that owns CipherMail Gateway is still called DJIGZO.
  • The S/MIME certificate selection links in the administrative web interface have been moved to a pulldown menu.
  • The German translation of the user portal has been updated.
  • The encrypt mode option "Force" in the administrative web interface has been renamed to "Allow (sender or recipient)".

2.6.0 - 2.8.5 (N/A)

Versions 2.6.0 through 2.8.5 were internal releases.

2.5.0 (2013-05-07)

New features

  • A page has been added where a MIME-encoded message can be uploaded for text extraction. This allows the administrator to see the text used by the DLP scanner for pattern matching.
  • PDF option "Send CC to replier" added. If set, a carbon copy of the PDF reply will be sent to the replying user.
  • S/MIME option "Skip import of untrusted certificates" added. By default all certificates from a signed email will be imported, even if they are untrusted. By enabling "Skip import of untrusted certificates", only trusted certificates are imported.
  • "Signing subject trigger" option added. This can be used to force signing of email if the subject contains a user defined keyword. Keyword can be removed if configured.
  • Password strength check added to the user portal. The minimum required password strength can be set by the administrator. By default you are not allowed to use your email address as your password, base your password on your username or use a keyboard sequence of more than five characters.
  • System page added where the server can be restarted and where Postfix can be stopped and started.
  • Three custom properties and templates added. These properties and templates can be used if the mail flow (defined in config.xml) is modified by the administrator and the changes require some user-configurable options.
  • A page has been added to the administrative web interface which can be used to send a test message.
  • French language support added to user portal.
  • Administrative users are automatically logged out from the web interface after five minutes of inactivity.
  • Backups are now compressed with gzip.
  • OpenJDK 7 is now supported.

Technical changes

  • The HTML text extractor for the DLP scanner now skips HTML comments by default. This makes it less likely to have false positives for some patterns.
  • The HTML text extractor for the DLP scanner now only scans the HTML body by default. This makes it less likely to have false positives for some patterns.
  • The HTML text extractor now also scans 'application/xhtml+xml' attachments.
  • "Dynamic" memory allocation is now enabled by default. The DJIGZO back end now uses a heap size of 0.6 times the available memory by default.
  • The back-end SMTP server no longer adds a 'Received:' header. This makes it easier to remove internal IP addresses from the received headers using Postfix header checks.
  • Changing the IP address filter of the administrative web interface no longer requires a restart of the web server. The filter settings are read from /etc/djigzo/ip-filter.properties.
  • The maximum inline body of PDF messages is now 256 kB by default. If the message is larger than that, it will be added as a text attachment.
  • Back-end logs now rotate once grown to 10 MB (was 5 MB).
  • The SMS option "Phone number allowed" is no longer enabled by default. Note: this is a non-backward compatible change since the default value changed. To revert back to the old behavior, enable the global "Phone number allowed" option.
  • sudo usage has been simplified. Scripts will now be executed from scripts.d.
  • Some jars updated.
  • Support for right-to-left (RTL) text added to the PDF encryption module.
  • Support for multiple SMS transports added.
  • The DLP scanner now also extracts the meta content of MIME parts. This can for example be used to block or quarantine certain attachment types. The attachment type is detected from the content of the attachment and not from the filename.
  • Comodo classes have been removed for now since the Comodo EPKI no longer allows certificates to be requested automatically.
  • Changing the automatic backup cron expression no longer requires a restart. The backup job will be rescheduled.
  • The signature algorithm identifier of a signed email changed between RFC 3851 and RFC 5751. RFC 5751 for example uses 'sha-1' whereas RFC 3851 uses 'sha1'. The Gateway now follows RFC 5751 by default. Some spam filtering systems however cannot handle the new RFC 5751 syntax. The SMIMESign mailet can be configured to revert back to RFC 3851 behaviour.
  • URL detection for the PDF module has been improved.
  • JCE policy manager page removed since it is no longer required with OpenJDK.
  • Most pages now close after applying the settings instead of showing a "settings applied" message.
  • The administrative web interface now checks whether regular expressions are valid.

Bug fixes

  • The HTML text extractor for the DLP scanner sometimes removed white space characters, which resulted in merged words.
  • Some internal James log files were not correctly rotated.
  • On Chrome, if an attachment was removed from the PDF reply page, the frame was not resized.

Miscellaneous

  • The reply link in the PDF is now a clickable image.
  • The look and feel of the administrative web interface has been changed. We moved some functionality to different pages. The SMS queue for example is now part of the Queues page. Most menu items can be dynamically extended to support additional Gateway modules.

2.4.0 (2012-05-30)

New features

  • Sign and encrypt tags can be added to the subject for incoming signed and/or encrypted email. Ref: GATEWAY-36.
  • Added signer and sender address mismatch detection. Ref: GATEWAY-21.
  • S/MIME encrypt mailet can selectively encrypt headers. This is mainly used in combination with DJIGZO for Android.
  • S/MIME encryption and signing algorithm can be set per recipient or domain.
  • Simple subject filter added which can be used to filter the subject using a regular expression.
  • Locale (i.e., language) can be selected on the user portal login and signup pages.
  • Command line interface tool added which can be used to set/get user properties.
  • Spanish translation for the user portal added. Translation by Diego A. Fliess.
  • Clickatell provider now supports additional parameters.

Technical changes

  • Logging has been improved. More information is logged and color coding has been improved. Ref: GATEWAY-42, GATEWAY-26.
  • Upgraded Bouncy Castle to 1.47.
  • LogLevel OFF added which can be used to completely disable logging for a specified class.
  • Loading speed of the preferences page has been improved.
  • The user no longer has to log in after the portal signup. They are automatically logged in after the signup process.
  • The packages are now signed with a new PGP key.

Bug fixes

  • The 8.4 PostgreSQL JDBC drivers were not compatible with PostgreSQL 9, which is the default version in Ubuntu 12.04. The PostgreSQL JDBC drivers have been updated to 9.X to remedy this issue. Ref: GATEWAY-56.
  • sudo added as a required package to the RPM spec file. Ref: GATEWAY-55.
  • PDF replies did not use the 'Reply-To:' header. Ref: GATEWAY-45.
  • Under certain circumstances, Unicode characters were incorrectly encoded when replying to an encrypted PDF message. Ref: GATEWAY-48.
  • Fixed compatibility bug with Internet Explorer 9. Ref: GATEWAY-40.
  • The RPM package installer now waits for PostgreSQL to be running before continuing the installation, to prevent database connection errors.

2.3.1 (2011-11-27)

New features

  • Support for One-Time Password (OTP) PDF encryption. The OTP can be obtained by the recipient after logging in to the portal.
  • Email can be encrypted with additional (escrow) certificates. Ref: GATEWAY-9.
  • The PDF reply page and quarantine viewer now support multiple languages (de, en, nl).
  • The message with the encrypted PDF can be digitally signed.
  • EJBCA integration added (certificates can be requested from an EJBCA server).
  • The login pages of the administrative web interface and user portal now contain a brute-force filter that blocks access for some time if an attacker tried to log in with many incorrect credentials in a short timeframe.
  • Added support for RedHat/CentOS 6.

Technical changes

  • The entropy of generated passwords is now 128+ bits.
  • The URL path for PDF and quarantine view has been changed from /external/* to /web/portal/*.
  • The portal functionality (PDF reply, external quarantine view) is now in a separate war file (djigzo-portal.war).

Bug fixes

  • The wildcard domains were not functioning correctly. Ref: GATEWAY-35.
  • Incorrect URL for multiple recipients when using OTP PDF encryption. Ref: GATEWAY-38.

Known bugs

  • In Internet Explorer 9, Compatibility View should be enabled for the web interface to work correctly. This bug will be fixed in the next release.

Miscellaneous

  • Some CSS changes: fonts are bigger, the background color is now white and other minor changes.
  • SMS settings moved from the main settings page to a separate setting page.

2.2.0 - 2.3.0 (N/A)

Versions 2.2.0 and 2.3.0 were internal releases.

2.1.1 (2011-08-16)

New features

  • Advanced S/MIME setting "Always use freshest signing certificate" added. If enabled, every time the sender needs to sign a message, the most recent (i.e., the latest "not before" date) signing certificate will be used. Ref: GATEWAY-14.
  • Advanced PDF setting "Only encrypt if mandatory" added. If enabled, PDF encryption will only be activated if encryption is mandatory. Ref: GATEWAY-22.
  • DLP setting "Quarantine on failed encryption" added. If enabled, when encryption is mandatory and a message cannot be encrypted, the message will be quarantined instead of returned to sender. Note: this required minor changes to the "DLP quarantine" template.
  • Quarantined emails can now be released as-is. When a quarantined message is released this way, no further processing is done and the message is immediately delivered.
  • The administrator can now specify how many rows the grid should show per page (users, certificates, MTA queue). Ref: GATEWAY-23.
  • The administrator can now filter for specific email in the MTA queue.
  • The MTA logs are now shown in "raw" format by default (i.e., in the exact same order as the log file). To view the MTA logs grouped on queue ID (the old behavior), the administrator should select "Grouped" ordering.
  • If a certificate chain is valid, the issuer of the certificate can be clicked on in the certificate viewer to show details about the issuer certificate.
  • New role ROLE_MOBILE_MANAGER added.
  • The command line tool can be used to add new charsets to the PDF encryption module, in order to use charsets that are not supported out-of-the-box by Acrobat reader. Ref: GATEWAY-20.

Technical changes

  • If a certificate was available for a recipient, a user object was always created for that recipient. The user is no longer added by default. A new S/MIME advanced setting "Add user" is added which can be used to specify if a user should be added when a certificate is available for a recipient.
  • Djigzo has the capability of adding certain headers to the signed and/or encrypted inner MIME part. This can be used to protect certain headers (for example the subject line). However there are some S/MIME gateways that cannot handle S/MIME messages with headers within inner MIME parts. Because interoperability is important, the subject header protection has been disabled by default. Ref: GATEWAY-31.

Bug fixes

  • With S/MIME "strict mode" enabled, S/MIME messages were only handled by the S/MIME handler if the recipient had a valid certificate with private key. If a digitally signed message was received for a recipient not having a private key, the certificates were not extracted from the message and the signature was not removed when "Remove signature" was enabled for that recipient. The message is now always handled by the S/MIME handler. Ref: GATEWAY-27.
  • Under certain special conditions, the base64 encoder of Javamail created lines with more than 76 characters. OpenSSL, which is used by some S/MIME gateways, cannot handle base64-encoded parts containing lines longer than 76 characters. Javamail has been updated to remedy this issue. Ref: GATEWAY-29.
  • When deleting a large number of messages from the MTA queue, the MTA queue could no longer be read until after the garbage collector ran. Ref: GATEWAY-32.

Miscellaneous

  • Some settings have been moved to advanced settings.
  • The BlackBerry and mobile settings have been moved to a separate page.

2.1.0 (N/A)

Version 2.1.0 was an internal release.

2.0.1 (2011-03-18)

Bug fixes

  • If a message was placed in quarantine because of a DLP violation and the 'Message-Id:' or 'From:' header contained a '%' character, deleting the mail from quarantine resulted in an error. This bug was reported by Andreas Beier. Ref: GATEWAY-15.

2.0.0 (2011-03-07)

New features

  • Data leak prevention (DLP) module added.
  • S/MIME strict mode added. In strict mode, additional checks will be done to make sure that the message will only be decrypted if there is a matching certificate for the recipient.
  • Delivery Status Notifications (DSN) are now supported. DSNs are transparently handled by the back end.
  • Header protection can now be disabled. Ref: GATEWAY-13.

Technical changes

  • Switched to Java 6.
  • Locally-generated notifications are now signed. If a locally-generated notification is received by the Gateway (for example because of email forwarding), the message is sent as-is to prevent mail loops.
  • Javamail updated to 1.4.4-final.

Bug fixes

1.4.1 (2010-11-11)

New features

  • The virtual appliance now allows you to specify which IP addresses are allowed to access the login page of the administrative web interface.

Bug fixes

  • Fix for "The PDF reply portal no longer attaches the uploaded attachment" (Ref: GATEWAY-12). This was a regression introduced by a previous bug fix (GATEWAY-4).
  • Fix for "The telephone number in the subject should be detected before removing the encryption trigger". Ref: GATEWAY-11.

1.4.0 (2010-08-23)

New features

  • Different certificate request handlers can now be added using a pluggable infrastructure.
  • Certificate request handler for Comodo has been added. With the Comodo certificate request handler, certificates from Comodo's managed PKI services (EPKI) can be automatically requested from the Gateway.
  • Certificates can now be requested in bulk. A comma-separated text file containing the request details can be imported. The certificates will be requested using the selected certificate request handler.
  • An email encryption header trigger has been added. Email encryption can be triggered using a pre-defined header, which is matched against a regular expression.
  • A certificate can now be automatically requested for a sender using the default selected certificate request handler, if the sender does not already possess a certificate and matching private key.

Technical changes

  • When a large number of certificates (more than 60 000) were imported, the certificates view in the administrative web interface was having performance issues. The certificate view has been optimized for this.
  • Upgraded to a new version of Apache CXF. The SOAP TCP port is now only accessible from localhost by default.
  • The virtual appliance has been upgraded to Ubuntu 10.04 LTS. Installing the Unlimited Strength Policy Files is no longer required.

Bug fixes

  • The PDF reply URL and body didn't support Unicode characters, only ASCII. The reply URL parameters are now UTF-8 encoded. The body is now UTF-8 encoded if it contains non-ASCII characters. Thanks to Benedikt Zorn for reporting the issue.
  • When creating certificates, the email address wasn't added to the alternative names, only to the subject.
  • Domains containing an underscore were accepted as a valid domain. This is incorrect, and the code that performs this check has been updated.
  • Java wrapper version upgraded to the latest version. Sometimes the Java wrapper was not able to automatically restart Djigzo when the wrapper detected that Djigzo wasn't running.
  • The update menu items in the virtual appliance console were incorrectly named. The menu items were named "Update" and "Upgrade", but they should have been named "Upgrade" and "Dist-upgrade".
  • Importing a PFX file containing a large number of certificates resulted in a timeout.

Miscellaneous

  • Some menu items in the administrative web interface have been moved to a left-hand submenu.
  • The SMS settings menu item has been moved to the SMS page.
  • The message template to edit should now be selected from a drop-down menu.
  • The restart and PDF import attachment wait animation has been replaced with an animated gif.
  • Added note to the virtual appliance documentation about reserving memory to prevent swapping. Thanks to Andreas Beier for his help in finding the cause of spurious crashes when running under ESX when the total memory used by all VMs was larger than the total host memory.

1.3.2 (2010-03-30)

New features

  • Subdomain matching can now be configured on the MTA configuration page.
  • PFX passwords can now be stored in the user preferences.
  • MTA authentication (SASL passwords) for external and internal relay hosts can now be set.
  • Virtual appliance now has Fetchmail support. This feature is disabled by default.
  • Support for Internet Explorer 8.
  • Debian 5 (Lenny) is now supported.
  • Multipart/alternative calendar items are now detected.

Bug fixes

  • When SELinux was enabled and Postfix was restarted by Djigzo, Postfix sometimes stopped working.
  • Upgrading with the RPM package wasn't working.
  • The owner and file mode of the TLS certificate was reset when upgrading the Debian packages.

New features

  • RPM packages for Red Hat and CentOS are now available. The installation guides have been updated with instructions for these operating systems.
  • S/MIME signatures can be selectively removed.
  • S/MIME can be selectively skipped for calendar items (text/calendar). Outlook cannot handle signed or encrypted meeting requests.
  • CRL downloader and SMS gateway can now access external resources via a configurable HTTP proxy.
  • Configuration files split into multiple files to make upgrades easier when the files have been changed.
  • Password setting "Send to originator" added. If it's enabled, generated passwords for the PDF encryption will be sent to the sender of the message.
  • The 'force signing' trigger can be used to trigger S/MIME signing of a message using a special email header.
  • Certificate Trust List added which can be used to allow or deny certificates.
  • Messages sent from BlackBerry (via BlackBerry Internet Service) can now be relayed through Djigzo.
  • Support for Mac OS X Java wrapper added. Patch submitted by Rainer Frey.
  • The virtual appliance now contains a firewall which blocks access to services that don't need to be externally accessible.
  • Most templates are now by default UTF-8 encoded. Templates now fully support Unicode.

Technical changes

  • Tomcat is now used by default instead of Jetty.
  • The 'Expired' column is now shown in red when a certificate is expired.
  • Original Message-ID of messages is retained if possible.
  • Subject triggers are now recursively removed.

Bug fixes

  • Signature check sometimes failed for clear-signed messages.
  • Backup and restore now works across different PostgreSQL versions.

1.3.0 (N/A)

Version 1.3.0 was an internal release.

1.2.4 (2009-09-01)

New features

  • Command line tool added for monitoring the MPA queue.
  • Authentication and authorisation against an external LDAP database is now possible.

Bug fixes

  • Some 'Received:' headers were sorted in incorrect order. Reported by Steven Geerts.
  • The MX setting on the MTA page was reversed. Reported by Steven Geerts.
  • The telephone number in the message subject was not picked up when the subject only contained the telephone number.
  • Djigzo did not start if the virtual appliance was given more than 2048 MB. Reported by Stefan Schwarz.
  • Encoded smime.p7m filenames are now recognized.

1.2.3 (2009-07-01)

Bug fixes

  • The CRL distribution point did not contain an issuer. When Outlook option SigStatusNoCRL was enabled, Outlook reported that the CRL was not available. The CRL distribution point is now moved to the end-user certificate. Reported by Mark van Voorden.
  • An error occurred if a CA certificate was not yet configured and 'apply' was selected on the CA select page.

1.2.2 (2009-06-02)

New features

  • Built-in CA added. The CA can issue certificates for internal and external users.
  • A telephone number specified in the message subject can be used as recipient for the SMS text messages. This feature is used for sending the PDF encryption password.
  • VMware tools can be rebuilt from the menu.
  • Large attachment are now supported when using the BlackBerry module.
  • "Force encrypt mode" added to overrule the noEncryption setting.
  • The administrator can see who (user, domain) is using a certificate.
  • Rows per page for the display grids can be set using a system property.
  • Certificate and CRL algorithms and more properties can now be viewed.
  • CRL certificate entries (the revoked serial numbers) can be downloaded as a text file.
  • A dialog is now shown when a network configuration error occurs.

Technical changes

  • Attachments not supported by the BlackBerry application are stripped. HTML-only mail is converted to plain text.
  • The root certificate is added to the chain when exporting certificates and signing messages.
  • CRLDistPointCertPathChecker added to certificate path builder. Critical CRL distribution points are now accepted.
  • SMS text messages now expire in 24 hours if not sent. This was 4 hours.
  • PDF replies are now disallowed by default.
  • Default S/MIME encryption algorithm is now 3DES because not all Windows versions support the stronger AES algorithm.
  • Password validity interval should now be set in minutes. Old settings will be automatically converted.
  • Jetty upgraded to 6.1.17.

Bug fixes

  • mail.mime.parameters.strict system property added. This is a workaround for mail created by Mac OS X. The Mac OS X mailer "forgets" to quote filenames containing spaces.

Miscellaneous

  • Some user settings in the administrative web interface have been moved to advanced settings.

1.2.0 - 1.2.1 (N/A)

Versions 1.2.0 and 1.2.1 were internal releases.
