Is there a way to forward mail to external users who have the same e-mail address domain as the internal users. IE internal users mail is firstname.lastname@example.org and the external users mail is email@example.com?
We are running SBS2003 using a pop connector to download mail from ISP. External users have individual mailboxes at ISP and internal users are on a "catch all" mailbox with routing rules setup on the pop3 connector. Forwarding of unresolved receipients is setup on the exchange box to send mail out to the external users from the internal users.
