I'm glad you asked. Feel free to make a cron script to grab this
handy, dandy net-lsearch-able list of relays I've found to have virus
infected users behind them and put it in /etc/exim4/infected-hosts.txt
Please don't abuse my server, be reasonable about your timing. It
gets updated several times a day, try to avoid fetching more than four
times a day, two should be enough.
Easy to impliment, as well. If you use exim4, add this to
# Virus spewing hosts.
deny message = $sender_host_address has been sending or relaying viruses. If you are now clean, please forward this message to email@example.com.
log_message = $sender_host_address is listed in infected-hosts
hosts = net-lsearch;/etc/exim4/infected-hosts.txt

Among other reasons. http://www.interhack.net/pubs/munging-harmful/
Treat the problem, not the symptoms. Report mail and news abuse.
Munging is accepting the problem.
