[Dovecot] corrupted inboxes

[Josh Burley]

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?
