While this won't fix the problem, it should be pointed out that you need 
to have an A record for the above hostname on your nameservers.  At the 
moment it is listed as NXDOMAIN (domain does not exist).

The mailertable is only relevant for delivering mail to their system, and
will not affect their ability to relay outgoing mail through you.

If the mail is coming from the above server, then you should be using the 
following entry in your access file:

	Connect:196.31.65.238	RELAY
not
	196.31.65.238		RELAY

if you are using a current version of sendmail.

If you are using SMTP AUTH then of course that should be set up correctly 
as well, as that will also affect outgoing relaying.
