While internal to the network, I can send and receive emails. However, when external, such as going to the internet, accessing yahoo mail, I get the following error:

Message from yahoo.com.
Unable to deliver message to the following address(es).

:
63.145.181.67 does not like recipient.
Remote host said: 550 5.7.1 ... Relaying denied.
Please check your mail first or restart your mail session.
Giving up on 63.145.181.67.

What does this mean and how do I fix it?

I have three cobalt servers, two are dns servers and one is a mail server. The dns servers are dns3.applelaptopbattery.com and dns4.applelaptopbattery.com. The mail server is pop3.getadeal.com.

I created a MX record on both DNS3 & dns4, added an A record on dns3 & dns4 for pop3.getadeal.com. Also, I added all the IP addresses for the email receipients of pop3.getadeal.com, pop3.getadeal.com, www.getadeal.com, and getadeal.com into the Relay for the following Hosts/Domains on dns3 & dns4. Also the email service is enabled on dns3 & dns4.

I then setup the email service on pop3.getadeal.com, added all the ip addresses of the email reciepients, the domain names, mail.getadeal.com, getadeal.com, www.getadeal.com,and pop3.getadeal.com to the relay box on email services. I then added getadeal.com and pop3.getadeal.com to the web aliases and email aliases.

I am perplexed as to why email is not working.

Help!!!!!! What does this mean and how do I fix it?
