My most recent mailserver stupid DoS was this sobig virus sending
100kb messages to my *-request aliases, which get processed by Mailman
at a very slow rate, virtually shutting down my listserver for a few hours.
Some global filters fixed things, but sobig.f didn't hurt on the actual
virus end, but on the virus to request addresses, and more recently the
million and a half bounces from servers who think I sent them a virus,
but in reality received a forged header.
