I am in the middle of setting up a new exchnage server 2k3 and need to know how i can setup our cisco routers(1720&1760) to translate MX RECORDS.. Or if some Cisco expert out there can tell me how i can setup this new email server on the router side to allow ingoing and outgoing mail, including webaccess. For the time being i have setup Nating for pc anywhere example:
ip nat inside source static tcp 5631 5631
ip nat inside source static udp 5632 5632
would this be the same style setup that i'd use for the mailserver expect substitute the ports with 80 and 25? What about the protocol?

Routers don't translate MX records. IOS has no clue what an MX record is.

As far as the router is concerned, protocols are irrelevant in NAT. All it knows about is ports. If a packet arrives on Port 80 and its been told to NAT Port 80, it will do so. It has no clue, nor does it even care, if the protocol operating across Port 80 is http or ftp or ssh or anything else.

So, yes, you use similar statements, and just substitute 80 and 25 as appropriate.
