Hi, I am receiving emails but not able to send, getting the following error messages. 

The connection to the server has failed.

Subject 'test'
Server: 'mail.bigpond.com'
Windows Live Mail Error ID: 0x800CCC0E
Protocol: SMTP
Port: 25

I have uninstalled and reinstalled Mail to no avail.  I am at a loss at what to do next.  Is anyone able to help?  Many thanks, Lee-Anne
