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).
IIRC, I've encountered that or a similar message (in TB 1.0.6) when the server uses SSL/TLS and the certificate is expired or not trusted, causing Thunderbird to pop up a warning, which gets ignored (since the user is doing something else while Thunderbird starts up) until the connection times out. 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.
I'm using with SSL/TLS with not trusted cert. Thanks for the info.
I'll try using my valid cert. If it doesn't happen with that, I'll be
much confident in it.
On another note, I'm testing it on another server using alternate port (994) for TLS, but Thunderbird refuses to connect to it. I wanted to run on alternate port so we can test well before cutting over to it.
Thanks,
John
