actually I just gor a list of the SMTP servers from our ISP and put them in
a group and added a rule that says...
ISP_SMTP Mail Server SMTP ALLOW
Internal Users
This way only SMTP mail being delivered from our ISP and internal users
comes through. Everything else is just rejected. Quick and dirty, but it
works, and no complaints so far. Only problem is that if our ISP changes
mailserver IP numbers or something.....
