I must have 1 email address from my email-domain (intern and external) that always send the mails to the external smtp-server.

mail domain is novellrocks.com
email address create is test@novelrocks.com

So when we send internal our external een mail to test@novellrocks.com it will be deliverd to the mailbox.
But for this mailbox I explicit wants that the internal mail is first send to an external smtp server thats relay it to the gwia and then delivers its to th mta and then to the po and to the mailbox.

In the past you could send een mail to gwia:test@novellrocks.com so it was deliverd external and then get it back through the gwia.
