If you don't like perl, I've got a C++ implementation that acts as an
SMTP server wrapper around sendmail here:

Thanks for the links, David. I will look and see if they are better
options than sid-milter.
Ok. Here is another pointer to milters to look at.

Suggested ones in order:
http://www.snertsoft.com/sendmail/milter-gris/ Greylisting Free
http://www.snertsoft.com/sendmail/milter-spiff/ SPF Free
http://www.snertsoft.com/sendmail/milter-sender/ CBV Pay
The others have their uses as well. It it is all a matter of tuning
your system to your needs.
The greylisting will kill 60% of the spam and 98% of the inbound viruses.
It is the cheapest as far as processing time to run. Then SPF gets the
left overs and kills about 1%. The milter-sender then kills off another
10%. It is the most expensive in processing time, so you run it last.
I run my own home brew of the milter-sender and milter-spiff, but have
worked with the author and watched his development. I highly recommend
his software.
The hardest part to installing his software is that "In order to support
B/W lists milter-* requires Berkeley DB 3 or better." So, sendmail and
makemap have to be rebuilt with a newer Berkeley DB than the default
of 1.85. He has full instructions, so it is not that bad.
