dovecot - Mar 2005 - corrupted inboxes

Hi all,
    Two users on our system have recently had trouble reading their 
inbox, and it seems to be a result of their inbox getting corrupted.

    In the most recent case, their Mailbox file (in /home/eric/Mailbox 
in this case), has the following as the first line:

cnw.igmg--

    Here's a piece of the logs below... if you look for "eric",
there's
a successfully delivery, followed a bit later by a POP attempt by
"eric"
that returns that the Mailbox isn't in mbox format.

    Any ideas?

Is this with v0.99.x? It has some random problems with mboxes.
dovecot-stable and 1.0-test releases have rewritten mbox code.

When I was having trouble with some users getting other users' mailboxes 
I tried upgrading to dovecot-stable-20050302 (dovecot-1.0-test59). After 
getting it installed and configured, though, half of the users could 
read their inbox fine, and the other half would only see a single email 
in the inbox (the oldest one, it seemed... separators not being 
recognized between emails for some users? weird...).

So, I went back to the original, and emailed you guys about the problem.

I'll try upgrading again this weekend, though, and report back if the 
"single email mailbox" problem happens again.

Thanks!
