Update Information:

fixes CVE-2015-3420: SSL/TLS handshake failures leading to a crash of the login
 process
- dovecot updated to 2.2.16

- auth: Don't crash if master user login is attempted without

  any configured master=yes passdbs

- Parsing UTF-8 text for mails could have caused broken results

  sometimes if buffering was split in the middle of a UTF-8 character.

  This affected at least searching messages.

- String sanitization for some logged output wasn't done properly:

  UTF-8 text could have been truncated wrongly or the truncation may

  not have happened at all.

- fts-lucene: Lookups from virtual mailbox consisting of over 32

  physical mailboxes could have caused crashes.
- dovecot updated to 2.2.16

- auth: Don't crash if master user login is attempted without

  any configured master=yes passdbs

- Parsing UTF-8 text for mails could have caused broken results

  sometimes if buffering was split in the middle of a UTF-8 character.

  This affected at least searching messages.

  trigger this for him/herself though.
- lmtp: Client was sometimes disconnected before all the output was
  sent to it.
- replicator: Database wasn't being exported to disk every 15 minutes
  as it should have. Instead it was being imported, causing "doveadm
  replicator remove" commands to not work very well.
