I've set up server 2003 with exchange 2003. I have my own domain name, 4pcfix.com. Everything internally is working. I've set up an host name with dyndns because I'm running off a dynamic ip at my house. I have NOT had my domain hosting company (ipower) direct the mx record to my dyndns host name yet. I set up a smtp connector on the exchange server but when I try sending an e-mail outside of my internal network I get the following error
server.4pcfix.com #5.5.0 smtp;550 bosauthsmtp15: Host 76.89.xxx.xxx: No unauthenticated relaying permitted>
I have a few questions. One, do I have to forward the mx record in order to send e-mails? If the answer is no then whats with the error above.
The error says No unauthenticated relaying permitted. Well there is no authentication option that i see in exchange like there is in Outlook for example.
Spamhaus shows my current ip on the PBL list but I'm not sure if I should remove it or not.
Any clarification of this would be greatly appriciated.
