[Dovecot] iPhone 1.1.1 problems.

[Mike Meyer]

I'm having problems with the iPhone client in the 1.1.1 version of the
iPhone software. Things with other clients work fine, and the iPhone
worked fine before it was upgraded to 1.1.1. Other phones on 1.1.1
failed. I'm still working on testing against the client with the
iPhone 1.0.2 software on it.

The problem is that the client simply doesn't connect to dovecot. I
can see the packets passing back and forth in a number of ways, but
haven't been able to see the contents. I tried turning on raw logging,
but don't get log files for accesses from the iPhone. What I get are
lines like so:

Oct 13 00:08:34 bhuda dovecot: imap-login: Disconnected: rip=xxx.xxx.xxx.xx2, lip=xxx.xxx.xxx.xx1, TLS

Turning off SSL both ways, and the message changes to:

Oct 13 18:21:38 bhuda dovecot: imap-login: Aborted login: rip=xxx.xxx.xxx.xx2, lip=xxx.xxx.xxx.xx1

Tweaking the logging in the firewall reveals something interesting:
apparently the phone makes the connection to 993, then dovecot drops
the connection, but the phone keeps sending to it (and yes, I've tried
setting the firewall to allow arbitrary traffic between the phone and
the server).

So, first question: is anyone who has clients using iPhone software
version 1.1.1 working willing to share config information?

Second question: suggestions for things to try to solve the problem?
(Other than talk to apple as that process is underway)? For instance,
a recipe to sniff the text of the interchange?

Final question: Any other information I can provide that might help
debug this?

      Thanks,
