We have several email accounts that we have set up to only be able to email within our Exchange organization; they are blocked from emailing outside the organization. I did this by simply creating a Connector attached to the First Routing Group (we only have one) which I set to the entire organization in scope, and set the delivery Restrictions to specifically reject messages from these specific accounts.
However now I am being asked if these blocked accounts can now email SPECIFIC external email addresses. To my knowledge I do not think I can be that selective with a block.
So what are my options? Is there a different way to set up a block such as this, yet it would still allow me to punch holes in it for specific external email addresses?
We are running Exchange 2003 SP2 Standard FYI. Thanks for the help!
