Attached is my 1841 security router config. Simple question. Device 10.2.1.6 is my e-mail server & I want it staticly routed through the 65.103.52.172 address, such that when it sends outbound mail the recipients mail server sees it coming from 65.103.52.172. Right now outbound mail appears to be from 65.103.52.169, so I am missing something in this static route. Please advise.

What is this line doing -
ip nat inside source static 10.2.1.6 65.103.52.172 route-map nonat
more specifically what is the route-map for ?

Thanks for taking a look Jon!
I also have a VPN coming in through this router and there is some VPN traffic from the remote location that needs access to the 10.2.1.6 server. So, I think the route-map was added because of that VPN so that traffic over the VPN does not get NATed going back to the remote location.

I suspect this line in your config
ip nat inside source route-map nonat interface FastEthernet0/1 overload
is taking precedence over this one
ip nat inside source static tcp 10.2.1.6 25 65.103.52.172 25 extendable
Please do this out of production hours and verify that your VPN traffic still works.

not sure you need the second route-map statement as you are covered in the first one.
try changing -
ip nat inside source static 10.2.1.6 65.103.52.172 route-map nonat
to
ip nat inside source static 10.2.1.6 65.103.52.172 route-map nonat

try changing -
ip nat inside source static 10.2.1.6 65.103.52.172 route-map nonat
to
ip nat inside source static 10.2.1.6 65.103.52.172 route-map nonat
These lines you provided are exactly the same, what am I changing?

Sorry about that, sometimes i'm a bit absent minded :-)
ip nat inside source static 10.2.1.6 65.103.52.172 route-map nonat
to
ip nat inside source static 10.2.1.6 65.103.52.172
