[Dovecot] Lost messages with Mozilla and dovecot 0.99.x

[John Peacock]

I have just moved our corporate e-mail over to qmail/dovecot and am very 
happy with the performance.  However, I have had two reports of messages 
going missing which may or may not be directly related to Dovecot.

I was able to observe this in action this morning:

1) I got the user out of their e-mail client (Mozilla 1.7.2) and forced 
an email to be delivered.  It showed up in Maildir/new.

2) I had the user log in using our webmail (Squirrelmail) and the 
message was visible to the client (and correctly moved to Maildir/cur).

3) The user then logged in using the Mozilla mail client and not only 
was the message not visible in the client, it was no longer on the disk!

4) This was completely repeatable, even if I deleted the .INBOX/index 
files and forced dovecot to rebuild.

For the moment I am thinking this is a client problem, but I thought I'd 
mention it just in case it rang a bell with someone.  I wound up 
installing 0.99.11 just for grins (I just moved these people to the new 
server and don't want to risk 1.00-test yet).

I'm also going to look at whatever debugging messages are available in 
dovecot; it would be useful to see a log of all imap transactions, not 
just login, so I could confirm that it is the client process requesting 
that the files be deleted and not somethink with dovecot itself (or some 
hardware failure).

Thanks

John
