Newbie: How to open up port 25 going into a 5505 for an email server?

[Jeff Rozar]

Do I create an SMTP Network Object and send TCP traffic throught NAT?

Or do I go to the ASDM's Configuration/Firewall, choose Public Servers, and choose Private Interface=inside, Public Interface=outside, set the private/public IPs, and choose SMTP as the service? This seems much simpler, but is it the correct way to do it?

I am using ASDM 6.4(5) and would like to use that versus the CLI.

Thanks!
