Relaying Not Allowed

Many Internet access providers require clients within their network to use their own servers for sending mail, as a policy intended to cut down on email spammers sending spam through other provider's servers.

Server Down

If you can do a successful connection check, and the above suggestions don't help, and a recipient continues to say that email sent from you does not arrive, and you are certain their address is spelled correctly, then one of the email servers between you and your destination is likely down.

Exploring More Mail Server Issues

Mail Server covers a broad category of services. Some errors are easy to diagnose while others require a bit of investigation. If you cannot send mail, the problem is likely a restriction by your ISP (Internet Service Provider) as many block the normal sendmail port 25, due to their own security concerns. This can be the case even if sending was working recently as some ISP's roll these changes through without warning.
