I am most familiar with sendmail where you can set up a filter
to send and error and the msg back to the MTA without accepting the
message first.=20

For example I use rules like:

spammer@spamdomain.com	"500 You Spammed Kenny...You Bastard!"
192.168.100.		"500 You Spammed Kenny...You Bastard!"

The maps DUL and RBL can also be used in sendmail.cf.
If you are on a dialup and use fetchmail you can still use the
DUL and RBL in procmail scripts.

If there is sufficient interest I will write up a short
example of how I use:

teergrube
procmail
sendmail

to filter SPAM.

I'll throw in some URLs for reference.

It may be a few weeks before it gets posted.

hence clamorous to be led to safety) by menacing it with an endless series
of hobgoblins, all of them imaginary.
