Large number of unscanned messages

[Bill Anderson]

I have a large number of messages that do not get scanned.  I have verified
that they are not whitelisted.  Most of the spam get's caught, however some
slip through without scanning.  What could be causing this or what is the
best way to diagnose the problem.  Here is the log entry:

Jan 16 15:26:33 arwen MailScanner[27051]: New Batch: Forwarding 1 unscanned
messages, 5099 bytes

Here is the header of an unscanned message:
