Hello Dovecot users,
The most important feature that this new release adds is the IMAPSIEVE capability, which allows executing Sieve scripts at IMAP events. It also adds the ability to obtain trace logs from Sieve execution at actual delivery (or from IMAP), rather than only using the sieve-test command line tool.
This release also fixes a bug in the Sieve extprograms plugin that has been bothering a few people for a while now.
- The address test now allows specifying the X-Original-To header.
- Implemented the Sieve imapsieve extension and its IMAP counterpart (RFC 6785) as a set of plugins. This allows running Sieve scripts at IMAP activity, rather than at delivery. There are also facilities for the familiar sieve_before/sieve_after administrator scripts. A user script is defined for a mailbox using an IMAP METADATA entry, whereas administrator scripts are configured using mailbox matching rules defined in the plugin settings.
- Adjusted the Sieve ihave extension to allow capability tests to be performed at runtime. This way, scripts can be written that work both at delivery and from IMAP.
- Implemented support for runtime trace debugging. This means that detailed information about which commands, actions and tests are performed is written to a file. That file is created in the configured directory, but only if that directory exists. This way, a particular user can be easily singled out for debugging. This works much like the Dovecot rawlog facility. The trace output is identical to what is produced using sieve-test with its “-t” command line option.
- Added a “sieve_user_email” setting that configures the user’s primary email address. This is mainly useful to have a user email address available in IMAP, where envelope data is unavailable.
- Implemented the dovecot-specific “vnd.dovecot.report” extension. This allows sending report messages in the Message Abuse Reporting Format (RFC 5965).
- extprograms plugin: Fixed epoll() panic caused by closing the output FD before the output stream.
- Made sure that the local part of a mail address is encoded properly using quoted string syntax when it is not a dot-atom.
The release is available as follows:
