I want to add an additional email domain to Exchange without it being automatically populated on everyone elses account. I've added it to the Recipient Policy but not ticked the box under the "Generator rules" section. I've also added the domain into my own AD account.
When I try to send an email to the email address on my AD account for this new domain, it returns with:
<account>@<domain> on 06/04/2007 12:34
You do not have permission to send to this recipient. For assistance, contact your system administrator.
<<testdomain> #5.7.1 smtp;550 5.7.1 Unable to relay for <account>@<domain>>
Any ideas what's not been configured right, or how to get around this issue without ticking the box?
