Your mail client is attempting to send mail via a box that is configured to
only relay mail that's been authenticated via user/password or whatever.  Make
sure your mail client is using the appropriate SMTP server.  Also try setting
"this mail server requires authentication" to true, and make sure that the
user/password you enter in that part of the mail client are correct for the
SMTP server.

It's hard to be more specific since I don't know what client you're using. 
This doesn't have much of anything to do with websites, either.

I'd say this is barking up the wrong tree, unless you're trying to send mail
to a domain that doesn't have an MX record.  That should give you a totally
different error message though.
