Comcast, my mail host, no longer supports Port 25 for my outgoing mail.  What can Iuse instesd?  I tried port 465 but that didn't work either. Here is the error message I receive: 

The connection to the server has failed.

Subject 'test'
Server: 'smtp.comcast.net'
Windows Live Mail Error ID: 0x800CCC0E
Protocol: SMTP
Port: 25
Secure(SSL): No
Socket Error: 10013

I tried using 465 as the port, as Comcast suggested, but that didn't work either.  They said it is a Microsoft issue.  Can you help me?
