As promised: I've zoomed in on a tcp session that goes haywire.
I've attached such a session in a pcap file: see attachment.
Looks like mozilla initiates an active close after receiving a 'OK
STATUS completed' but dbmail failes to properly close the session,
leading to the client sending RST packets that trigger the broken pipe
problem.
I guess serverchild.c needs some serious refactoring... :-)

I don't really think its the acl stuff that's causing this. 1.2.3 has
similar problems with mozilla type clients, it just got much worse on 2.x.
I'll investigate and see what I can come up with.

Someone should sit down with a tcpdump or ethereal-type protocol
analyzer and
try getting to the bottom of this! KMail does not support the Namespace
extension, and might not support ACL either. So something about one or
both
must be a little bit buggered, either by us or Mozilla; only a true
patch will
tell :-)

This sounds very similar to the problems I am having with
Mozilla/Thunderbird and 2.0rc2. Only access to the INBOX, doesn't
check for
mail when I tell it to, etc. So far my only solution has been to use
Outlook

I'm guessing it's a client related issue.
This occurs when I access dbmail-2 from a thunderbird-0.5 client that
has several accounts with many folders configured.
I've also moved my dbmail-2 imap server around to a UML instance on
the same machine as my dbmail-1 server, and also to a totally
different machine in the same network.
In all cases: thunderbird triggers the closed pipe error, whereas
squirrelmail and ilohamail work just fine.
I've finally tested this with mozilla-1.6 with only one account: same
problem. One additional thing I noticed though: on first accessing a
new account, mozilla and thunderbird hang while 'Getting folder ACL'.
Closing and restarting the client gives me access to the INBOX, but
no other folders. weird...
I've tested with balsa and with sylpheed. Oops. Same broken-pipe. No
problems reading email though.
