There is no record pointing to the domain itself.  It points

All our incomming mail comes via one IP into a firewall, gets port
forwarded to the mailserver and is processed.

We have no problems receiving mail.

All mail sent is shown to come from 'mail.movielink.net.au' with
the IP of the firewall.  That IP currently resolves to 'mail.movielink.net.au'
which does not match with <[EMAIL PROTECTED]> and the error 451 is
sent back to us.

Should I have that IP reverse lookup to resolve to 'movielink.net.au'
instead?
