can cisco (6509/sup720/IOS) route based on destination port? I am
trying to configure it such that all internal hosts connecting to a
certain port outbound (any destination) are redirected to an internal
host running a service on that port.

Version 12.2(17d)SXB6, RELEASE SOFTWARE (fc1)

I don't know 65xx but you can try :

Cisco# ip nat inside source static tcp ?
A.B.C.D Inside local IP address

I forget :

ip nat outside source static tcp

what about the reply packets, if a client send a packet out to
www.google.com on smtp port, it expects a reply from www.google.com
otherwise it will drop it right?

I need to configure it such that www.google.com can be down and my mail
sever will still respond as www.google.com to the originating host.
