Perhaps the fact that the original sender is not in the mail gateway's
domain or even close to it (as in the case of almost all the spam I've
received through this list and other NetBSD lists) can be used as a sign. 
Then, a more thorough check can be performed. This way a cursory glance is
all that is needed at first, with only a very small percentage of the
mails which are passed through going through the detailed (procmail?) 
check.

Oop..  here comes another. Oh boy..  a dental plan. Just what I wanted.
