Re: webmail AUTH problem
I happend to stumble into a problem with webmail auth recently. It's described in http://tikiwiki.org/tiki-index.php?page=WebmailDev#comments. The problem isn't smtp but pop3 related. A quick solutions (well: hack) is mentioned.
Try to telnet localhost 110. If you get an answer longer than 100 chars, (i'm getting something +OK some.server.domain.tld Cyrus POP3 v2.2.3 server ready 910591426.1077059945 at some.server.domain.tld here at a test sever, which is quite a bit longer) it's it.
