Why won't Outlook Express let me send Email to someone at Juno?

Question

When trying to send Email to someone at Juno I receive the error message below. I am able to send Email to this user from my ISP's Web Mail interface, but not from Outlook Express 6.x.

The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was '[e-mail]'. Subject 'return from trip date', Account: '68.168.78.100', Server: 'smtp-server.roadrunner.com', Protocol: SMTP, Server Response: '550 relaying mail to juno.com is not allowed', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79

There are a great form of explanation why. it relatively is a corrupt outbox folder, or your companies SMTP server ought to be experiencing subject.

From your error message, it looks like you have Time Warner. We were having this same error, and after multiple phone calls to Time Warner's technical support we have the problem fixed. They kept insisting that it was an error on our computer, but it was their outgoing mail server. We now have our email rerouted to a different outgoing mail server and the problem is fixed.

Have you tried to send email to anyone else from Outlook Express? That would be the first thing to check. It sounds like Outlook Express could be set up incorrectly. That's what it sounds like to me. Outlook Express can be difficult to set up.
