I've been testing alpha4, and every once in a while my client (Thunderbird 1.5 RC1) tells me the dovecot isn't a valid IMAP4 server. This is usually (maybe always) when I first bring up the client up. If I just ask the client to get the mail again, it does so happily (without any errors). I must say I found dovecot as a pleasant surprise. We have been using UW. Which didn't scale well. I was considering going to cyrus, but dovecot seems to have given much (if not all) of performance improvements without all the hassle of conventing all the existing mbox mail to maildir.

When the user clicks OK, Thunderbird tries to proceed but the connection is reset, triggering the totally confusing error message. I don't know if it's it - you should have noticed any such message box, but maybe you didn't think about it. It could also be something similar, with an unexpectedly broken connection in common. -- Magnus Holmgren

Clutching at straws but do you have login_greeting_capability = yes in dovecot.conf? I have encountered at least one client that would not talk to dovecot at all without this option because the client wanted to see IMAP4rev1 in the greeting. Last time I looked I couldn't find any explict requirement for this in the various RFCs though.
