http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta4.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta4.tar.gz.sig

Lots of fixes since beta3, but apparently there are still a few bugs left:

• Is SORT working?
• APPEND seems to have problems in some setups.
• Still some SEARCH TEXT problems? Or Squat indexing problems?
