Its a HUB transport rule. I do not have my lab machine online right now, but it would look something similar to this:

Basically you would do the following:

- Create a distribution group, and then add the users you do not want the person to have the ability to email
- Create a new HUB transport rule, and then do the following:

"From people" (select user), "sent to a member of a distribution list" then "send rejection message to sender with enhanced status code".

I'm not sure if I understand your question properly.

Are these users in the same organisation?

Have you tried to set up Exchange Transport rules?

this is for internal users within the same domain.

We want to be able to block userA from sending any emails to anyone other than to userB.
