dovecot - Feb 2005 - File isn't in mbox format - Couldn't open INBOX

I cannot reproduce this error everytime, but it seems to happen when
Outlook tries to delete the first message (the first message in the
file, message on top) in the /var/mail/user file.

I tried looking through the mailing list but came up blank. Is this a
known problem?

I can fix this problem by editing the file manually and fixing the file.
If I delete the first 2 lines (in the example below) and make sure the
Inbox file starts at "From ..." it works fine again.

Here is the log:

What Dovecot version? There have been several fixes for mbox in 0.99.x
series, and 1.0-tests have completely rewritten (better and faster) mbox
support.
