I have a problem that I can not resolve. Maybe someone can give me a hint on what to do. I recently moved my exchange server from my home to my office. Before, users had to authenicate before mail would be relayed. That was only internal users. Since I changed my domain name, I figured it would be wise to rebuild the exchange server and start from scratch. Everything went well on the installation. When I opend the server up mail from the internet cam in without any problems. If I am at the office and on the internal network, I can send and receive mail fine. But this is my problem. I can access the server from outside (my home) and pull the mail (using outlook express). But when I try to send mail I get the "550 5.7.1 Unable to relay for user@domain.com" message. I tried to set up outlook express to send an username and password to authenicate then relay but it all I get is a username/password window and it will not accept any good username/password.
I don't want my server to fall into the hands of the spammers and relay bastards. How can I set it up to require a vaiid username and password to authenicate?
