Hello
I have a Cisco ASA 5505. What is the command and/or the place in ASDM to configure sending  and receiving mail only from Postini's network range? (64.18.0.0-64.18.15.255).

thanks

If External mail server ip = 1.1.1.1 and Internal mail server ip = 192.168.1.1 then....

access-list outside_access_in extended permit tcp 64.18.0.0 255.255.240.0 host 1.1.1.1 eq smtp
access-group outside_access_in in interface outside

access-list inside_access_out extended permit tcp host 192.168.1.1 64.18.0.0 255.255.240.0 eq smtp
access-list inside_access_out extended deny tcp any any eq smtp
access-list inside_access_out extended permit ip any any
access-group inside_access_out in interface inside

You would obviously need to change  little depending on what you have already and if the mail server is located on inside/dmz etc.

I am setting up this one to take the place of my SonicWall. Then I will be migrating to a dual firewall configuration with ISA in the DMZ pointing to FE/BE mail servers on the inside. (both will be ASA 5505's)
