Problem sending emails from Outlook Express Ver6

[me]

I am trying to use Outlook Express Ver6 instead of Eudora. I can't
seem to send e-mails from it. When I send a test to myself I get the
error:

The message could not be sent because the server rejected the sender's
e-mail address. The sender's e-mail address was (MY ADDRESS)
.. Subject 'TEST', Account: 'incoming.verizon.net', Server:
'outgoing.verizon.net', Protocol: SMTP, Server Response: '550 5.7.1
Authentication Required', Port: 25, Secure(SSL): No, Server Error:
550, Error Number: 0x800CCC78

Can anyone suggest what is wrong? Must be something dumb.

TX
yes
