What configuration tool did you use? It might be worth contacting
the author and letting him/her know that forwarding rules need to use the
outbound interface.

That's probably the case. They'll reject it based on the domain
used, not on the ip address from which you connect. For this reason,
this isn't a problem that can be fixed by an ipchains or ipfwadm firewall.
One good option you have is to feed all your mail through the
sendmail running on your own box. Sendmail will pass email along directly
to the destination so you don't have to use your provider's smtp server.
Cheers,
