http://dovecot.org/releases/1.1/dovecot-1.1.4.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.4.tar.gz.sig

- SORT: Yet another assert-crashfix when renumbering index sort IDs.
- ACL plugin fixes: Negative rights were actually treated as positive
  rights. 'k' right didn't prevent creating parent/child/child mailbox.
  ACL groups weren't working.
- Maildir++ quota: Fixes to rebuilding when quota limit wasn't
  specified in Dovecot (0 limit or limit read from maildirsize).
- mbox: Several bugfixes causing errors and crashes.
- Several fixes to expire plugin / expire-tool.
- lock_method=dotlock could have deadlocked with itself.
- Many error handling fixes and log message improvements.
