Change that to
mydestination =3D $myhostname, localhost.$mydomain
IMGATE receives no mail locally, it is all realyed to the exchange box

Relay domains should be something like this.
relay_domains =3D $mydestination,
$mynetworks,
=20
hash:$config_directory/relay_domains
Where relay_domains is text file containing
Domain.to.relay BLAH
Other.domain.com BLAH
RHS doesn=92t matter, and remember to postmap the file.

Use transport maps
transport_maps =3D
hash:$config_directory/transport
Where tranport is a text file cotaining the domain that is to be
delivered
To the exchange server on the LHS and the IP of exchange on the RHS
Domain.to.relay smtp:[ip.of.exchange]
Other.domain.com smtp:[ip.of.exchange]
And postmap the transport file
