[Dovecot] Message display corrupted or missing in Netscape 7.0 and Mozilla 1.3

[Steven Enderle]

Hi,

a few days ago, we switched our site from pop3 to imap. We are running 
about 20 users with Netscape 7.0 on a FreeBSD-4.8 Server . I installed 
dovecot 0.9.99.1 via the freebsd-ports collection, which was as easy as 
make install and start dovecot. Our users mailboxes are still standart 
mbox format in /var/mail/(user), as it is default in Freebsd.

Now we suffer from a realy ugly problem, which was arising after the 
switch from pop3. When Netscape is newly started, it works fine as 
expected until Netscape displays messages corrupted or stops displaying 
them completly. I also cannot forward them in that state or open or 
delete them in any other way. The only way to get it working again is to 
quit Netscape, exit quickstart and restart Netscape again.

It just hangs on a bunch of messages or all of them.

The user notices it like this: There are three windows displayed in 
netscape mail:

1. imap folder view
2. message list of the current folder and
3. the currently displayed message.

The Folder view and Message List in Netscape is always fine, so the 
Subject and sender, time, etc is always displayed in the List. The 
problem occurs then on some messages when i select them for reading. The 
Message Display below the message list just stays empty (also opening 
the message in a new window doesn't help) or the "title bar in the 
Message Display" stays empty (no subject, sender, time etc) and the raw 
email starting with header, raw html email and encoded attachment is 
shown below, each line followed by another blank line, like this:

== start corrupted email
X-UIDL: 8793f170f0430909

Return-Path: <frank.xx at xx.de>

Delivered-To: xx at mdn.de

Received: from mailrelay1.xx.de (mailrelay.xx.de [212.114.153.xx])

	by xx.de (Postfix) with ESMTP id D31B7A88F

	for <xx at mdn.de>; Wed, 18 Jun 2003 08:55:07 +0200 (CEST)

Received: from ntmail1.xx.de (ntmail1.xx.de [212.114.155.xx])

html and stuff following...

== end   corrupted email

One could read it, but its realy ugly.

It seems, that if i delete a lot of messages in sequence (the morning 
spam), i can force to happen that problem earlier. It always hangs while 
deleting my spam.

I like dovecot a lot, it was easy to install etc and works pretty fine 
except that it still seems to be in beta-stage. Now i would switch to 
courier/uw-imap until dovecot is ready, but the mbox format dovecot is 
using seems to be pretty uniq? I think, the users could keep their 
/var/mail/Username-INBOX, but wouldn't they loose their email folders? 
Is there any way to switch the software in a easy way? Or will there be 
a near future release which will fix that? What about the cvs version?

Thanks for you help!

Best regards

Steven
