I have Exchange 2003 and want to know if I can set it up so that certain mailboxes are able to receive emails but can only send emails to other mailboxes within our domain - user@abc.com can receive from anyone but can only send to others @abc.com. Can this be done? And to take this a step further....is it also possible to restrict that mailbox to only receive and send from the same domain they are in - user@abc.com can only send and receive from @abc.com email addresses? Thanks,Kris

Hi, This should help: http://www.msexchange.org/tutorials/MF009.html Leif

Thank you. Can you also restrict a user to not only receive from their own domain - but also add a specific set of email addresses outside the domain they can receive from? I found the check box where I can restrict to authenticated users only, and there is the option to receive only from a specific list, but when I go to add I can only select from our domain. Can I added, for instance, a yahoo address outside our domain so can receive from anyone in our domain and a specified list of other non-domain users?Thank you. Kris
