554 Cannot send message

[pearl]

Hello, I got the following message when testing my free yahoo email account
in Outlook 2007:

"Send test e-mail message: Your outgoing (SMTP) e-mail server has reported
an internal error. If you continue to receive this message, contact your
server administrator or Internet service provider (ISP). The server
responded: 554 Cannot send message."

It's been like this for weeks, and I cannot figure out what's wrong. I have
other other email accounts through Outlook are all working fine except for
this one. What can i do to fix this?

Is it a PAID Yahoo Mail account? Freebie accounts at Yahoo.com (USA)
don't get access to their POP/SMTP mail hosts. Some non-USA Yahoo
domains still allow access to their mail hosts for free accounts. You
didn't say which Yahoo domain you use for your e-mail account.
