Sending email with Yahoo address via Vista windows email?

I have just installed Vista on my computer and I have problems sending emails from my windows mail. I can receive messages but not send. I have a yahoo email account and have no problems sending from yahoo and no problems when I was using XP.

This is the error message I get from the server:

Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Subject 'Test message let me know if you got this ASAP', Account: 'pop.mail.yahoo.com', Server: 'SMTP.MAIL.YAHOO.COM', Protocol: SMTP, Port: 25, Secure(SSL): No, Error Number: 0x800CCC0F

I have double checked all my configurations and they seem to be correct. Can someone help me please?
