Incoming mail on PIX 515

**ps3cheats** · 25-Mar-2007, 10:19 PM

Question: We have a Cisco PIX 515e and use an outside company to filter our email for spam. I need to configure my PIX to allow only a set list of IP addresses to allow incoming mail into the exchange server.

What do I need to do the config to block all incoming mail except for a set list?

object-group network filtering-servers
network-object host
network-object host
.....

access-list outside-in permit tcp object-group filtering-servers host eq smtp

by default it will block anything not explicitly accepted on the outside interface
