RE: latest spam-milter

[Ron Snyder]

I seem to remember seeing something (msg id unknown, 0 length email check)
similar to this when sendmail aborts a check (as it does when the sending
host is listed in an RBL (we don't have SA doing the RBL checks, we have
sendmail doing them). 

This might help you at least duplicate the actions of sendmail.
