I have recently gotten Dovecot running on my Solaris 5.8 mail server in order
to replace UW IMAP. I'm currently testing it out with mail clients popular
amongst my users. It's been working very well, with one vital exception.
Apple Mail on OS X 10.4 is not completing authentication (I don't think
it's even getting that far).
All I'm seeing in the syslog for attempts with Apple Mail (for both IMAP
and POP3) is a single line per attempt:
Jan 29 17:20:01 paradox dovecot: [ID 107833 mail.info] imap-login: Disconnected:
rip=X.X.X.X, lip=Y.Y.Y.Y, TLS handshake
This is even with verbose for auth and for SSL. I know syslog plays well with
mail.warning and mail.debug and mail.notice, so I'm not quite sure
what's
going on there. Nothing shows up in authlog or messages either.
The OS X 10.5 Apple mail client works just fine, as do Thunderbird and even
Eudora. There did not seem to be any coverage of this when I googled and
went through the dovecot archives, so I'm thinking it might be some weird
interaction between that particular client and the SSL/shadow implementation
in dovecot (Things work in UW IMAP for the client).
Any suggestions? thanks!

Have you looked at the network traffic to see if it even tries to send anything to Dovecot? Maybe it just connects and then sends nothing. -------------- next part -------------- A non-text attachment was scrubbed...

Just wanted to follow this up. I was contacted off list be a few people and confirmed myself that the issue is that the Mac OS X mail client for Tiger (10.4) does not work properly if it is assigned a non-standard port for IMAP or POP3. Once I brought dovecot into production at the standard ports, the Apple mail client for Tiger worked just fine.
