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.

Changelog v0.4.14:

* 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
+ 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 "" 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:
