dovecot - May 2018 - Released Pigeonhole v0.4.24 for Dovecot v2.2.36.

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.
