Shouldn't that be 'user@[literal_ip]' ? It's worth a go anyway.

The Exchange box should have some kind of hostname that it recognises
addresses for, so you should be able to send to
'user at exchange_hostname'. All you need to do is configure the Unix box
to resolve 'exchange_hostname' to the internal address. If the Exchange
box uses a simple hostname, just set the address in /etc/hosts. If it
only recognises an FQDN, you'll have to set that up in the DNS.
