I have 3 bellsouth.net (Yahoo mail) accounts tied to my Window's mail account.  I receive all three on my Windows Live Mail application on my laptop.   For some reason one out of the 3 stopped receiving mail on Oct 25.  I have no idea why.  I get this message:

Unable to send or receive messages for the Bellsouth ((xxxxxxxxxxx) account. Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity.

Server: 'pop.mail.yahoo.com'
Windows Live Mail Error ID: 0x800CCC0F
Protocol: POP3
Port: 995
Secure(SSL): Yes

Any idea of what is going on?  I can still receive the messages on my cell phone, and I can see them if I go to yahoo mail, I just don't get them on Windows Live Mail anymore.
