Log Message:
Upgrade dovecot to 1.0rc1.  Changes:

* PAM: If user's password is expired, give "Password expired" error
  message to the user. Now actually working thanks to Vaidas Pilkauskas
* Relicensed dovecot-auth, lib-sql and lib-ntlm to MIT license. See
  COPYING file for more information.
* Abuse prevention: When creating a mailbox, limit the number of
  hierarchies (up to 20) and the length of the mailbox name within
  a hierarchy (up to 200 characters).
* mbox: If saved mail doesn't end with LF, add it ourself so that the
  mails always have one empty line before the next From-line.

+ Added --with-statedir configure option which defaults to
  $localstatedir/lib/dovecot. ssl-parameters.dat is permanently
  stored in that directory and is copied to login_dirs from there.
+ IMAP: Support SASL-IR extension (SASL initial response)
+ Support initial SASL response with LOGIN mechanism. Patch by Anders
  Karlsson
+ Added PLAIN-MD4 password scheme. Patch by Andrey Panin.
+ Added support for XFS disk quotas. Patch by Pawel Jarosz
+ If another process deletes the opened mailbox, try to handle it
  without writing errors to log file. Handles the most common cases.
+ Added TLS support for LDAP if the library supports it.
- SEARCH command was more or less broken with OR and NOT conditions
