OK - my configuration is different.  I route everything through my Linux
gateway, and then onto the DSL router, which means that I can do this
(as all packets hit the internal interface on my linux box).

In your case, is it possible to add a static route on the netgear box to
point to your mail server?  This would mean that the internal addresses
would be routed correctly, but it may affect the external access
(depending on whether the NATing or routing takes priority).
