SMTP proxy to another Internet host Andre Vaux 07-19-2004

Is is possible to forward/proxy SMTP to another internet host? A bit
like PAT but to an external address instead of an internal one. Got a
bit of a problem and losing mail.

i.e.

All traffic recieved on
Internethost1:25
is forwarded/proxied to
Internethost2:25

Is this possible running Cisco 837 DSL router? (12.2)

Thanks

Andre

        Yes, use a route-map. The gotcha is you'll need to redirect
        the re-mapped packets on the SMTP host. Here's a writeup I
        did that should help.
