I have just had ATT Uverse installed for phone and internet.  I am unable to connect to my e-mail account.

 I get this message: 

The connection to the server has failed.

Subject 'Fw: organized confusion'
Server: 'smtp.att.yahoo.com'
Windows Live Mail Error ID: 0x800CCC0E
Protocol: SMTP
Port: 25
Secure(SSL): Yes
Socket Error: 10013

Can anyone help and tell me what to do?
