I have a PIX 520 that NATs all outgoing activity to a single public IP address. Our MX record is not the same public IP; mail services that do reverse DNS lookup to protect from spoofs and spam dump our email...how do I configure the PIX so mail goe...
I believe that's true also. Recently tried to enter aaa accounting (ver 5.2) command and it wouldn't let me. A call to TAC found a 'hybrid configuration' for which the fix is to change outbound list to an access list.
