Error Message while sending

[Alyssa]

Hi this error code shows up when i try to send an email, What do i do???



The message could not be sent. The authentication setting might not be
correct for your outgoing e-mail [SMTP] server. For help solving this
problem, go to Help, search for "Troubleshoot Windows Mail", and read the
"I'm having problems sending e-mail" section. If you need help determining
the proper server settings, please contact your e-mail service provider.

The rejected e-mail address was '(e-mail address removed)'. Subject 'Re: is it
working', Account: 'pop.telus.net', Server: 'smtp.telus.net', Protocol: SMTP,
Server Response: '550 <[email protected]>: Recipient address rejected: User
unknown', Port: 25, Secure(SSL): No, Server Error: 550, Error Number:
0x800CCC79

The error message is telling the truth:
"<[email protected]>: Recipient address rejected: User unknown"

There is no recipient with that email address.
