David,

I put that in the static filter like you said but then I never received the
email when I sent it from my etbu.edu account to my cablelynx.com account.

Lets say my internal ip address on my PSN for my mail server is 10.100.1.10
I have an alias created on my external interface called MAIL and it is using
ip 63.71.26.5

When I put <USE IP ADDRESS> 10.100.1.10 MAIL and save it, the mail is never
delivered.

Any suggestions?

You should configure a Static Address Mapping (under NAT) for this.

For example, if your internal mailserver is 10.100.1.10, and 63.71.26.5 is
on the MAIL alias:

<USE IP ADDRESS> 10.100.1.10 MAIL

These mappings control /outbound/ NAT.  By default all outbound traffic is
NATed to the EXTERNAL gateway interface. Static Mappings change this.
