John,
You're not telling us which MTA you are using, but the most excellent Exim
(www.exim.org) makes it easy to reject connections from individual as well
as entire IP blocks.
You just drop the IPs into /etc/exim.conf:
host_reject_recipients = : 208.169.22.0/24 : 204.198.135.70 : 209
.90.19.2 : 202.36.148.5 :
Failing that, you could always use an ipchains rule to drop connections from
the offending domain, something like this:
/sbin/ipchains -I input 1 -s [IP address] 25 -d 0/0 25 -p tcp -i [eth0 or
whatever interface you've got] -l -j REJECT
Provided of course that you have ipchains support compiled into the kernel.
