Hello,

I am having a slight problem with Mailscanner in that occasionally
messages do not get scanned at all.  Running Mailscanner version
4.44.6, sendmail 8.12.8 (I know, I need to update that).  Problem only
occurs a couple of time a day out of about 4,000 emails/day.  Of
course, all the ones that I catch are spam/virus that should have been
caught in Mailscanner, but were completely missed.  On all of these
messages, there is no header information to suggest that it was even
scanned, and the logs show no scanning to have occurred.

relay=[{internal mail server}] [x.x.x.x], dsn=2.0.0, stat=Sent
(Requested mail action okay, completed)

Sometimes there will be multiple recipients, sometimes just one.  I
have verified that there are no specific rules for any of the
individual users, or the relay servers.  I'm not even sure if this is
a Mailscanner issue or a sendmail issue at this point.  With the
exception of these few messages, everything is working just as
expected.

Thanks in advance for any help!
