My preferred way to block this kind of spammer is to block by sender
address. In my Exim config file, I have:
# Manual spam-blocking: any address matching a patten listed in
# /etc/exim/spammers is blocked from sending mail to us.
sender_reject = /etc/exim/spammers
And /etc/exim/spammers looks like this:
# See section 7.16 of the Exim spec for rules on the patterns
# in this file.
^chris@.*wafer\.com$
^Sheila.*@msn\.com$
sales@tice\.com\.tw
trafficmagnet.net
powerhiring.com
[... several more ...]
This is a very cheap and effective way to keep out a certain type of
spammer, since it tells them to buzz off as soon as the SMTP "MAIL FROM"
command is received. (I use SpamAssassin for the rest, and it works
pretty damn well!)
