dovecot - Feb 2004 - UW-IMAP -> Dovecot : patch to remove nasty "internal messages" from UW-IMAP ?

Hello there,

We want to move from UW-IMAP to Dovecot (mbox format), works like a 
charm, but UW-IMAP has that bloody habbit to make a stupid message in 
all his mailbox files :

 From MAILER-DAEMON Thu Apr 19 10:30:01 2001
Date: 19 Apr 2001 10:30:01 +0200
From: Mail System Internal Data <MAILER-DAEMON at mailhub2-vil.isdnet.net>
Subject: DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA
Message-ID: <987669001 at mailhub2-vil.isdnet.net>
X-IMAP: 0987630138 0000000001
Status: RO

This text is part of the internal format of your mail folder, and is not
a real message.  It is created automatically by the mail system 
software.
If deleted, important folder data will be lost, and it will be 
re-created
with the data reset to initial values.

Is there any patch / trick / whatever to avoid that such "stupid" 
message to be not served by dovecot ?

Thanks,
/Xavier

Many of the scripts that do the conversion remove this message.

I used perfect_maildir.pl to do my conversion. It was more or less 
dead-on, but had the habbit of marking some unread messages incorrectly 
as "read" after the conversion.

I've attached a patch which "fixed" this in my case. This patches 
against perfect_maildir.pl v0.2.

The main problem I have is that I have more than 700k boxes... And I 
cannot (yet?) affording to convert them into
maildir (even if it is more efficient.....)...

I don't really recommend using Dovecot with mbox at the moment. I'll
probably add support for "folder internal data" messages for rewritten
mbox support.
