How do I fix relay 550 undeliverable email error?

[Guest]

I have set up a group of contacts. When I try to send the email out it comes
back saying the email is undeliverable. The email doesn't go out because the
550 relay keeps denying it. Is anyone else having this problem?

Hi,

To resolve this behavior, contact your ISP for help. The e-mail client does not cause this behavior. From a messaging client standpoint, there are no solutions for customers whose ISPs
block all SMTP Relay traffic.

Please refer to the following Knowledge Base article for more information.

You receive a SMTP relay blocks error message when you send e-mail messages in Outlook 2002 and Outlook 2003 (290842)
