1) Are you sure the senders From address is not being spoofed?
2) If you are positive it is them, go to www.completewhois.com and
look up their contact info. Call them to stop. If spam continues,
report them to their ISP, then up-stream provider, etc.
3) Oddly enough they are using Postini as their anti-spam system, so
obviously they are not fans of receiving spam.
4) If your firewall is capable of ACL's and blocking IP addresses,
then make note of the IP address(es) that the spammer is using to send
email from to your email server and block them. However, if they are
spamming you, then they are spamming other people, so report their
activities to their ISP and up-stream ISP if their ISP is ignoring
your requests.
