I can receive, but not send.  It has worked in the past, but I can't pinpoint any incident that may have caused a problem.  I contacted my ISP (Cox Communications) and we checked my settings.  Everything is correctly set up with regard to my SMTP address, etc.  They told me it was a Windows Live problem.  When I attempt to send, the message sits in my outbox for several minutes and then I receive the following error message: 

 A time-out occurred while communicating with the server. 

Subject 'test mail' 

Server 'smtp.cox.net'

Windows Live Mail Error ID: 0x800CCC19 

Protocol: SMTP Port: 25 

Secure(SSL): Yes
