On my dedicated server, I have Postfix installed for sending email through the websites. One of my clients hosts their email with a third party so we have MX records set up on the domain.

However, when sending any Postfix emails from the server, they do not get the emails. I think since the domain is pointing at the server itself, it tries to send mail to itself, but there is nothing on the server to handle the email for that domain. (There are mail accounts for other domain which are working fine.)

How do I get Postfix to use the domain's MX records to send email?

Server is Ubuntu 8.10 with standard LAMP stack. I have Webmin installed, and a control panel called "Matrix" provided by the host.
