> Hello Dovecot users,
> Here's the Pigeonhole release that goes with Dovecot v2.3.2. You will
> need this release for Dovecot v2.3.2, because the previous v0.5.1
> release will not work. No changes were performed since the 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:
> Refer to 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.
