Yes indeed. Same virus too. I actually got blasted from 2 different IP
addresses and did a couple of things

1. blacklisted their IP forcing the email to be tagged as {SPAM?} and
spam action to delete
2. put their IP in /etc/mail/access with 'DENY'

Is there a way to automatically block floods of virus from 1 IP addres.
perhps a new action called 'Virus Flood'
Actions are delete, quarantine etc?

Maybe there is and I've overlooked this..Apologies if thats the case.
