I've got port 25 outbound blocked at my firewall. It only allows my designated mail servers to talk to the internet via port 25, this way in the unlikely event we do contract a virus that sets itself up as an SMTP engine it wont do any damage to my outbound bandwidth, and only internal bandwidth will suffer...now since I've gotten rid of the hubs and put switches in I think that only that machine will suffer providing its not scanning the subnet.
