Vista - I seem to be able to receive emails but not send

Hi, im trying to use the Windows Email for my Yahoo account
Ive been told to use
ingoing server as pop.yahoo.mail.com
outgoing server as smtp.yahoo.mail.com

I can receive my emails just fine, but i cant send any, what do i need to do?

This is the error message i get:

The message could not be sent. The authentication setting might not be
correct for your outgoing e-mail [SMTP] server. For help solving this
problem, go to Help, search for "Troubleshoot Windows Mail", and read the
"I'm having problems sending e-mail" section. If you need help determining
the proper server settings, please contact your e-mail service provider.

The rejected e-mail address was @yahoo.com'. Subject 'Hi', Account: 'Yahoo',
Server: 'smtp.mail.yahoo.com', Protocol: SMTP, Server Response: '530
authentication required - for help go to
http://help.yahoo.com/help/us/mail/pop/pop-11.html', Port: 465, Secure(SSL):
Yes, Server Error: 530, Error Number: 0x800CCC78

Make sure you have send authentication enabled.
Go to Tools, Accounts, select that account, Properties, Servers.
The box for "My server requires authentication must be checked.

I have had a similar problem and did not receive any error messages. Emails would just sit in the outbox but I was able to receive incoming mail ok. I found that there was a problem with one of the emails in the outbox. I deleted it and all the rest were able to be sent ok. Hope this helps.
