IT Employment
When people come in and plug into my office LAN
they get this message "550 relaying mail to "so & so.com" is not allowed" They can not reply or forward a message when they use Outlook, but they can receive.
How can I fix this problem?

You are probably hosting your own domain and it conflicts with the forwarding rules set on your own Exchange Server. For about the last three years one of the security roll up packages for Exchange switches off this type of forwarding as it is used by spammers. You are getting the mail in through POP3 OK as it is not covered by this, but SMTP is blocked to prevent relaying.
Look up "mail relaying" on the web and see if that has the same symptoms as your problem.

Here is what I am dealing with, Sprint sets up the office dsl, we get an earthlink account. I have agents that come in a connect with there laptops using Microsoft Outlook.
They can receive and send newly drafted e-mails, but they can not replay or forward received e-mail. They get "550- relaying to sam@wherever.com not allowed"
