We have an SBS 2003 server which has a catch all account running for the mail. All is ok on the internal side of things and VPN users can send and recieve ok. THere is an external user that has the same domain in his email it is just a seperate mail box off the catch all. I can send mail to him from hotmail etc but internet users get a bounce back. We have setup the user as an external contact but the Exchange server wont let it out?
