Sorry, the authentication problem still wasn't actually fixed in beta6. Now, this time I tested every possible authentication case that it really works. I'll soon create a CVS branch which is going to stabilize into the 1.0 release. I won't add new features there so it shouldn't really get broken anymore, at least because of new features.. So, two changes in this release: + Added shutdown_clients setting to control if existing imap/pop3 processes should be killed when master is. - Master login fixes, PLAIN authentication was still broken..
