Add domain to Whitelist in Exchange 2010
This really is something Microsoft missed a trick on, I mean how could they leave a simple whitelist out of the GUI, for shame. That being said I’m going to show you how to do it, they could have made it a lot easier though!
First open up the Exchange 2010 Management console, once that’s open Expand Organization Configuration and click on Hub transport.
Once the screen refreshed, in the main window click on the Transport Rules tab.
Now we’re going to create a new Transport rule that we can add domains to which we don’t want Exchange 2010 Anti Spam to scan or filter.
In my example, I’ve called mine “Allowed Domain” so I know what this Transport rule is for. I’ll do one from scratch for you.
On the tight hand side of the Exchange Management Console Window click New Transport Rule
Once that’s done all we need to do is give it a spam rating. To do this Highlight and Tick the action called set the spam confidence level to value
Once you’ve ticked this you’ll see the window below populate and by default gives it a Confidence Level of 0 which is what we want so it won’t get scanned.
Simply click Next and Finish and you’re all done. You can always amend this Transport rule later to add other domains.
Hope this gets you out of a sticky quibble.
