Error code received:

Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Subject 'Fw: Shriner's Trip to Topeka, Kansas', Account: 'pop.charter.net', Server: 'smtp.charter.net', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10053, Error Number: 0x800CCC0F

I can send the same emails through a gmail account, but with windows mail, there are the above codes I receive after it times out.

I have tried the idea of changing the port from 25 to 587. no good.

Any others ideas?
