Hello Dovecot users,

Here is the Pigeonhole release candidate that goes with the Dovecot v2.3.2 release candidate. Much like version 0.4.24 for Dovecot v2.2, this release consists mostly of fixes that accumulated over the last few months. Beyond that, this release contains the new IMAP FILTER=SIEVE capability, which was also released earlier with 2.2.24 (with a few additional fixes).

Changelog v0.5.2:

• 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.

• The Sieve address test caused an assertion panic for invalid addresses with UTF-8 codepoints in the localpart. Fixed by properly detecting invalid addresses with UTF-8 codepoints in the localpart and skipping these like other invalid addresses while iterating addresses for the address test.
• 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:
