I'm seeing what looks like file corruption with recent versions of maildrop. If I'm having mail delivered to a traditional mbox file, as opposed to a Maildir structure, incoming mail is overwriting a portion of the existing file so that mail is either getting corrupted or lost entirely.

I assume this is a maildrop problem since I have maildrop set as my DEFAULTDELIVERY local delivery agent in /etc/courier/courierd.

I first noticed this with the courier-users list, which appeared to have had little or no traffic since the 30st of October (highly unusual!), so I unsubscribed and resubscribed, and although my confirmation came through, my welcome message didn't. The 30th of Oct is when I updated from courier 0.38.2 to 0.40.0.20021026.

The problem is reproducable. If I back out to courier-0.38.2 it goes away, but if I upgrade again it recurs. It doesn't appear to affect mail delivered to a Maildir, since this has been coming in normally since my upgrade, and only a few addresses get stored in a flat mail file, which includes the postmaster address as well, which I also noted was devoid of traffic since the 30th!

Has anyone else noticed this problem? Sam, are you aware of anything that might be causing this? I'm going to stay at courier-0.38.2 until I get this figured out, and I'll be able to receive traffic on courier-users as well :-)
