How do I fix error message " 503 valid RCPT command must precede"

[Guest]

When I try to send emails from Outlook 2003 I get a system administrator
email in my inbox saying the following:

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

Subject: test after reinstall
Sent: 11/08/2005 08:43

The following recipient(s) could not be reached:

'(e-mail address removed)' on 11/08/2005 08:43
503 valid RCPT command must precede DATA


What's going on?

HI,
The server responded: 503 valid RCPT command must precede DATA

means you must check your email before trying to send mail. The mail server
requires authentication, which can be achieved using one of these methods:

1. Pop before smtp -- check your email for new mail before trying to send
email. This adds your IP address to a relayhosts file and allows any email
to be sent from that IP address for up to 30 minutes. After 30 minutes you
have to authenticate again.

2. Configure your email client to authenticate automatically by checking the
"my server requires authentication" box in your email configuration. You
will be able to send mail without having to "pop" your mail box first.
