Got the same problem here. 
The server is Gentoo, with Courier-imap-ssl. The connection is lost *very* often. 
(Often enough to force me to use Outlook)

well, I can confirm the bug for 0.6+ trunk thunderbird and 0.6 release. it is
really annoying and one of the most make-thunderbird-look-bad-bugs in the thing
:-) and should be taken care of.

this sounds like a dupe

What do you mean by "disconnections"? Do you get an alert that says the server
has disconnected? Or do things just spin not doing anything? Please try a recent
trunk thunderbird build (from the last couple days) and let me know if it still
happens. If it does, an imap protocol log would be interesting:

IMAP log file

I was able to reproduce the bug with Thunderbird 0.6 (couldn't figure out how
to get a CVS build for windows) on win2k with IMAP SSL (log attached). It
happens when browsing folders on an IMAP server. After having changed the
folder a few times, I get an alert saying: 'Server disconnected.
The server may have gone down or there may be a network problem'.
The server is running courier-imap version 3.0.2-r1. The only thing I can see
in the server logs are a bunch of LOGINs and LOGOUTs.

As far as I can tell this is not a duplicate of bug 209188 which has completely
different symptoms: it makes the thunderbird icon spin indefinitely while this
bug makes a popup window appear, stating "Server xyz has disconnected. The
server may have gone down or there may be a network problem".

Also, I can confirm this with thunderbird 0.7.1 running on RH9 and connecting to
courier imap on freebsd and suse.

The problem persist in the latest version 0.7.2.

you need to limit the number of imap connections tbird will cache to 4, imap
server settings panel of your account setup, by clicking the advanced button,
and changing the default 5 to 4. Your courier imap server by default limits the
number of connections from a single ip address to 4 (this number can be
increased on the server side as well)

I think that it solves the problem

This indeed works, but why does thunderbird disconnects so badly from the server
when a single connection from the pool is closed by the remote side?

the server connects, and then disconnects immediately - that's rather rude, and
we got an unexpected error from the networking code. The fix was to check for
this new error code and put up an error message.
