Looking at this, it seems it's MX_BUSY being set too low, just as David
pointed out earlier. mimdefang-multiplexor killed the slave, and
instructed Sendmail to tempfail the message. Sendmail should have
logged another line just after it got 'MAIL FROM', (grep for
iA2HfX9j017902 in logs). It will give you an idea for how long
MIMEDefang was processing the email, before it gave up. If what David
pointed out to you is correct, the time difference will match your
current MX_BUSY seting (give or take couple of seconds). Try boosting
MX_BUSY to 600 (10 minutes) or even 900 (15 minutes).
BTW, don't let huge mails go through SpamAssassin. Anything larger than
say 100k isn't likely to be spam, and it will take *really* long time
and huge amount of memory for SpamAssassin to digest large emails.
