Block forwarding of emails to some but not all outside domains

Users are setting up rules to forward emails to outside email addresses.  Due to our HIPPA policy we need to disable automatic forwarding to everything except for the few allowed outside addresses.  Automatic forwarding should still work to pagers (@alphapage.myairmail.com), internal address (higher and sub domains), and a few trusted facilities (different domains).  We also do not want to affect our Mobile 5 and 6 PDA devices.

Our servers are Exchange 2003 SP2
Most of our clients are Outlook 2003
We also use mobile 5 and 6 PDA's

What you need to do is go in to ESM, Global Settings, Message Delivery.
On the Properties of * you need to disable automatic forwarding. That will stop the rules based forwarding. Then add each domain separately in there and enabled automatic forwarding.

For things like pagers, use contacts on the User Account. That is unaffected by the Message Delivery properties. You can also use that for one offs, for example forwarding to a user's personal address at Hotmail, rather than allowing blanket forwarding to the Hotmail.com domain.

Sorry I left off an important part.  We share exchange with multiple domains.  I am still new to this but there are three domains that would be affected by doing a global setting.  Is there a way to do this for only one domain or set of exchange servers?

On another note I contacted the other domains and asked if this is something that can be reached globally in which case Sembee has the correct answer.

Its an all or nothing setting. That is why it is in the Global Settings. It applies to all servers in the Org.

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

The only way that might work is a variation of the block SMTP traffic method

You would have to put domains in to the connectors and then have multiple connectors. It would take some experimenting to get correct, but that is about the only method I can think of that will work.
