[Dovecot-news] Released Pigeonhole v0.4.16 for Dovecot v2.2.26.0


Hello Dovecot users,

Here’s the definitive 0.4.16 release. There were no changes since the release candidate.

The reported replication issues are still open, since we haven’t been able to reproduce them so far.

Changelog v0.4.16:

  • Part of the Sieve extprograms implementation was moved to Dovecot, which means that this release depends on Dovecot v2.2.26+.
  • ManageSieve: The PUTSCRIPT command now allows uploading empty Sieve scripts. There was really no good reason to disallow doing that.
  • Sieve vnd.dovecot.report extension:
    • Added a Dovecot-Reporting-User field to the report body, which contains the e-mail address of the user sending the report.
    • Added support for configuring the “From:” address used in the report.
  • LDA sieve plugin: Implemented support for a “discard script” that is run when the message is going to be discarded. This allows doing something other than throwing the message away for good.
  • Sieve vnd.dovecot.environment extension: Added vnd.dovecot.config.* environment items. These environment items map to sieve_env_* settings from the plugin {} section in the configuration. Such values can of course also be returned from userdb.
  • Sieve vacation extension: Use the Microsoft X-Auto-Response-Suppress header to prevent unwanted responses from and to (older) Microsoft products.
  • ManageSieve: Added rawlog_dir setting to store ManageSieve traffic logs. This replaces at least partially the rawlog plugin (mimics similar IMAP/POP3 change).
  • doveadm sieve plugin: synchronization: Prevent setting file timestamps to unix epoch time. This occurred when Dovecot passed the timestamp as ‘unknown’ during synchronization.
  • Sieve exprograms plugin: Fixed spurious ‘+’ sometimes returned at the end of socket-based program output.
  • imapsieve plugin: Fixed crash occurring in specific situations.
  • Performed various fixes based on static analysis and Clang warnings.

The release is available as follows:


Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release and don’t hesitate to notify me when there are any problems.
