Restricting Exchange to send mail from just one domain name

We appear to have an issue with our Exchange 2003 server. It is service packed and has SP2.  Is there a way of ensuring that any mail that is sent from the exchange server is from only one domain.  Ideally I would like to know how to restrict the exchange to only allow mail to be sent to the internet from @abc.co.uk and also internally from either @abc.co.uk or abc.local.

Any ideas.

Thanks for your help

You can set it up to only allow abc.com domain to relay. You do that in the connector
No idea what the above post is on about.
This has nothing to do with "the connector", presuming that the poster means an SMTP Connector.

Recipient Policy controls the email addresses on the accounts. As long as the accounts are configured correctly, email should not escape with the wrong email address.
However to answer your specific question - no there is no way to stop Exchange from sending out an email with a domain on it that is listed in its recipient policy but is not valid on the internet. If that is happening to you, then you need to investigate why the accounts are configured incorrectly, rather than trying to deal with consequences.

Forced accept.
