HI,

IIRC you create an AD Contact and mail enable it with the external users SMTP address. Then on the properties of that contact you say "reject messages from" and enter the mailbox. Even though the address is external Exchange will still do an AD lookup and find the address and restriction parameters.

You can create transport rule for this. With the rule you can send a bounce back email to user or silently delete the email.

As far as  I can tell the transport rule will allow you to block all messages and allow some. I need to block some but allow the rest. I s there a way to do this with the transport rule?

I will try the AD contact  and  post the results.

Creating an AD contact with restrictions seem to work.

Thanks.
