Changelog entries since current oneiric version 2.8.2-1ubuntu2:

postfix (2.8.3-1) unstable; urgency=low

  [Wietse Venema]

  * 2.8.3
    - Cleanup: postscreen(8) and verify(8) daemons now lock their respective
      cache file exclusively upon open, to avoid massive cache corruption
      by unsupported sharing.
    - Bugfix (introduced with Postfix SASL patch 20000314): don't reuse a
      server SASL handle after authentication failure. CVE-2011-1720

  [LaMont Jones]
  * Ack ubuntu fixes for multiarch. Closes: #620326, #625674
