I have MS Exchange set up on an W2K server and can only send and receive e-mails through it in house. A and MX records are correct on all servers. All services are started up and running correctly. If a user sends an e-mail via say AOL, the mail goes out and doesn't return an unable to send error. When someone trys to send an e-mail outside, an undeliverable error comes back saying unknown address etc... I have a firewall and Exchange is set up as the STMP mail service. Any ideas as to what I'm missing here?
