Please help with forwarding...

My goal is to have my firewall forward all mail for the domain
'domain.net' through to an exchange server behind the firewall.

This is the output of trying to send a test message from another
domain.

mgargiullo@domain.net... Connecting to grizzley.domain.net. via
esmtp...

grizzley.domain.net. config error: mail loops back to me (MX problem?)
>>> QUIT

It then tries the back up MX server

I have tried this from the FAQ:

]There are a couple of additional cases where you don't actually want
localdelivery, and thus adding domain.net to class w is not the right
fix:
]
]When relay.domain.net should just be acting as a forwarder, e.g. a
firewall/gateway box. The proper fix could be to set up a mailertable
entry for domain.net

My mailertable file looks like this

domain.net smtp:[192.168.0.3]

local-host-names contains the hostname of the firewall

Log Sample(One error and One Completed where I received the mail):
