I've been experimenting with dovecot-1.0-stable on Solaris. Storage format is mbox. Dovecot, in test, runs in parallel with an UW IMAP, with dovecot running SSL-only on port 994.
It seems to work to some extent:
* dovecot runs
* authentication works
* SSL works
* all manual IMAP functionality checks seem to work fineHowever, I'm running into issues with IMAP clients.
Null client: I started by using telnet as a client, and talking IMAP manually. Seems OK.
Mutt: "mutt -f imap://my.imap.server:994" seems to work well, although mutt keeps reporting details about the SSL certificate, informs me that it belongs to the proper server and is a valid Globalsign-issued certificate -- and keeps insisting I either reject it or accept it once.
Apple Mail (Panther's version, 1.3.11 (v622)) works, though it seems to have problems with large mailboxes. Then again, it had these same problems with other IMAP servers as well.
Thunderbird doesn't work at all. After some waiting, it bums out and reports:
Unable to connect to your IMAP server. You may have exceeded the maximum number of conenctions to this server. If so, use the Advanced IMAP Server Settings dialog to reduce the number of cached connections.
Note that it never even shows an authentication dialog, and the only thing I see in dovecot's log that relates to Thunderbirds attempt is:
dovecot: Jul 20 09:41:09 Info: imap-login: Disconnected:
Inactivity [131.211.143.87]
I'm at a loss as to what's causing this. On the one hand, dovecot seems operational, on the other hand at least one client can do nothing with it.
All debugging/logging options are enabled. What am I missing?
