Hello Dovecot users,

Here is the Pigeonhole release that goes with the new Dovecot v2.2.36 release. Apart from the changes that were already in the RC, this final release adds one new feature: a plugin for the IMAP FILTER=SIEVE capability. The is a vendor-defined feature that adds the ability to manually invoke Sieve filtering in IMAP.

Changelog v0.4.24:

• Implement plugin for the a vendor-defined IMAP capability called "FILTER=SIEVE". It adds the ability to manually invoke Sieve filtering in IMAP. More information can be found in doc/plugins/imap_filter_sieve.txt.

• Fix assert panics triggered by empty messages that are being forwarded using redirect or vnd.dovecot.report. This does not likely normally occur, but this is seen as a result of certain benign failures in object storage.
• Make the length of the subject header for the vacation response configurable and enforce the limit in UTF-8 codepoints rather than bytes. The subject header for a vacation response was statically truncated to 256 bytes, which is too limited for multi-byte UTF-8 characters.
• Sieve editheader extension: Fix assertion panic occurring when it is used to manipulate a message header with a very large header field.
• Properly abort execution of the sieve_discard script upon error. Before, the LDA Sieve plugin attempted to execute the sieve_discard script when an error occurs. This can lead to the message being lost.
• Fix the interaction between quota and the sieve_discard script. When quota was used together with a sieve_discard script, the message delivery did not bounce when the quota was exceeded.

The release is available as follows:
