[Dovecot-news] Released Pigeonhole v0.4.16.rc1 for Dovecot v2.2.26.rc1


Hello Dovecot users,

The upcoming release includes quite a few new features for a change. The most important ones are the Sieve discard-script feature and the new vnd.dovecot.config environment items. Documentation for these features can be found in the package itself.

Please test these thoroughly.

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 candidate and don’t hesitate to notify me when there are any problems.
