Problem-sending Yahoo mail-Outlook 2000

I cannot send Yahoo mail via Outlook 2000. I have configured the Outgoing server to be “smtp.mail.yahoo.com” which should be correct. I have also followed Yahoo’s instructions on setting up all of the POP3 info. I am able to receive mail. I readon Yahoo that it’s possible that delivering mail prior to sending would not login to the Yahoo site, therefore finding the SMTP Host (which is the error I receive).

Help, please.
