[Dovecot] Duplicate E-mail Problem

Hello all,

Definitely congrats on the 1.0.0 release!

Anyway, I'm having a problem, that may or may not be related to 
Dovecot.  Specifically, duplicate (and sometimes triplicate) emails are 
appearing.  These emails have exactly the same queue ID, so its not that 
they were sent multiple times.  These dup emails do not show up to me ever.

Postfix is being used as the SMTP, and it hands it over to procmail.  I 
set up procmail's verbose logging feature for that user and on the 
duplicate emails that he receives, it shows only ONE write to a file for 
that specific subject of email.  Tonight / this morning I'll be tracking 
down to see if this duplicate for sure happens in IMAP.

Note: Its possible that part of the problem is he leaves two IMAP 
clients open at the same time (Netscape I think).  I'm going to verify 
that with him.

Any ideas?  I'm NOT trying to blame Dovecot, I'm just trying to explore 
options.  Right now its looking fairly bad for Dovecot though....I mean, 
what else is there after the mail is delivered to the appropriate place 
in the mailbox?

Software versions:
postfix 2.3.8
procmail 3.22
dovecot 1.0.rc28
