Just a quick question:

on the inside interface access list on an ASA 5510 (if i am running exchange 2007 on an inside network for instance should i have an access list which allows tcp network eq smtp or should i just allow host email_server_ip eq smtp?  If i allow entire network do i invite a potential mail relay problem?


I have this problem too.
