I know I didn't start this thread but I have a very similiar problem, so I apologise for hijacking this, hope no one is offended.
I am trying to do the same thing route smtp traffic through to an exchange server behind a PIX506 and a router. the router would appear to be forwarding all traffic to the firewall (as expected) but the firewall refuses to route smtp to the exchange IP.
below are configs of 506.

interface ethernet1 auto

nameif ethernet1 inside security100

I think I may be a little confused about the structure of the rules as I have setup a SMTP any rule that should allow the smtp traffice access, and a static route through the firewall for the smtp traffic.
I am using the pix device manager to setup rules but this isn't exactly straight forward as far as logically creating rules.
Any help is much appreciated.
