主题: Dovecot-1.1.9 release candidate

http://dovecot.org/tmp/dovecot-1.1.9.rc.tar.gz

There are a couple of a bit larger changes, so would be nice if a few
people tested this on different setups before I released the final
v1.1.9.

Changes since v1.1.8:

    + deliver: Added rejection_subject setting, which is used for
      rejected mails.
    + pop3: Prevent clients from looping forever trying to fetch an
      expunged message.
    + If login process crashes, log the IP address that (maybe) caused it.
    + If core dump limit is 0, add "core dumps disabled" to startup log line.
    - mbox: Fixed assert-crash with pop3_lock_session=yes
    - dbox: Fixes to handling maildir-converted files.
    - Auth cache wasn't working correctly for all fields (e.g. allow_nets)
      with blocking passdbs (e.g. mysql).
    - pgsql: Handle reconnecting to server without failing auth lookups.
    - Berkeley DB memory/resource leak fixes.
    - maildir: Fixes to handling over 26 keywords.
