Outlook 2002 " Relaying denied. Proper authentication required."

[Jon V]

Ok I have just recently switched aver to a new domain for
a web site. I went through the configuration stuff in
outlook under the accounts and it connects to all the
servers and sends the test message just fine. If i try to
send anything to anybody but me it says undeliverable.
This includes emails on the same domain. I get the
following message:

Your message did not reach some or all of the intended
recipients.

Contact your ISP for help - perhaps you need to use different credentials.

Ok thanks for the info. I did attempt to contact the ISP
and they told me to open port 587, which I did. It still
does not seem to be working. Any other ideas?
