Getting 550 Authentication is required for relay

Hi All,

Am getting the following error when trying to send from Outlook 2003 SP2:
550 Authentication is required for relay.

I have setup Outlook to authenticate my outgoing SMTP, however, it does not
appear to be doing so. I enabled logging and snipped the following from the
OPMLog.log file:

The stars were already there...I did not add them.

In another part of the OPMLog.log, I am seeing this:

2007.04.03 13:15:34 POP3 (mail.douglas-associates.com): Port: 110, Secure:

Clearly, Outlook is authenticating on receive. However, it does not appear
to do so when sending. Is there something else I should be checking?
