I haven't had time to read through the Dovecot mailing list yet, so there are likely some reported bugs that haven't been fixed yet. I'll try to get to them next week in San Francisco. (Probably can't get much done this week in Tokyo.) In the mean time here's v2.2.11 with some new features.

        + acl plugin: Added an alternative global ACL file that can contain
          mailbox patterns. See http://wiki2.dovecot.org/ACL for details.
        + imap proxy: Added proxy_nopipelining passdb setting to work around
          other IMAP servers' bugs (MS Exchange 2013 especially).
        + Added %{auth_user}, %{auth_username} and %{auth_domain} variables.
          See http://wiki2.dovecot.org/Variables for details.
        + Added support for LZ4 compression.
        + stats: Track also wall clock time for commands.
        + pop3_migration plugin improvements to try harder to match the UIDLs
          correctly.
        - imap: SEARCH/SORT PARTIAL reponses may have been too large.
        - doveadm backup: Fixed assert-crash when syncing mailbox deletion.
