Corrupted e-mails

[Jonathan Belson]

Hiya

For the last few months, I've had a problem where a small number (less
than ~1 in 1000) of e-mails get corrupted.  All I have in my Maildir
is something like the following two lines:

Return-Path: <gvhtvxhxnv at sbcglobal.net>
Delivered-To: jon at localhost

In case case it's a spam so it's no great loss, but I've had it happen
to important e-mails too.

Here are the appropriate lines from my maillog:

Aug 18 05:35:17 dookie qmail: 1092803717.270465 new msg 2018
Aug 18 05:35:17 dookie qmail: 1092803717.270808 info msg 2018: bytes 6860
from <gvhtvxhxnv at sbcglobal.net> qp 66137 uid 82
Aug 18 05:35:17 dookie qmail: 1092803717.283085 starting delivery 1895:
msg 2018 to local jon at localhost
  <snip>
Aug 18 05:35:32 dookie qmail: 1092803732.535421 end msg 2018

The original e-mail looks to have been ~6.5kB.

Here is my .qmail, which runs SpamAssassin on the incoming e-mail for
this account:

|/usr/local/bin/spamassassin | /usr/local/bin/maildir /home/jon/Maildir/
#./Maildir/

I'm inclined to blame SpamAssassin since I saw a similar problem when
I had it misconfigured before - that was easy to track down since it
wrote error messages in the system log left (missing p5 package).  This
time there are no error messages, and the problem only occurs very
occasionally.

Has anyone else seen this before?  Any clues on what could be going
wrong?  Disabling SpamAssassin would make e-mail unusable since I
get hundreds of spam e-mails a day.

Cheers,
