We had the same damn thing happen to us, but it was the W32.Navidad virus
(or some strain thereof), which was proliferated across about 300 addresses
(only about 15 local).
The best way I found was to use a mailing list (such as Majordomo) and
restrict posting to local addresses and/or a flat file of acceptable addresses.
Thank god our internal users didn't get hit, and we spread the word faster
than the original message could get anybody!
