How do you fix the error "503 Valid RCPT TO <recipient> must pre.

[Guest]

When trying to send an email message using Outlook, it always comes back
undeliverable with the error message " 503 Valid RCPT TO <recipient> must
precede DATA". Any ideas on what I need to do to fix this problem?

Thank you very much!

Hi,
It means there is no TO address in the message..
If you are using a script be sure to make sure the recipient fields are set
properly..

That is the only time I've seen it is from form misconfigureation. most
clients usually refuse to send with no recipients..

You may need to authenticate to your outgoing server (set that up on the
"Outgoing server" tab of the account). If that doesn't work, could you
tell us the version of Outlook you're running?

I tried authenticating and it didnt help.

I am running Office 2003.

Any suggestions?
