You need to talk to your provider about how to use a VPN and actually send mail, other than through their web mail.

Time Warner does not allow you to contact their mail server to send mail unless you are connected to the internet using their internet service. That is how I understand their policies (from half a world away), Your VPN by it's very nature [retends you are from somewhere else. It offers privacy by pretending you are from, well where ever symantecs endpoint is really. Russia, China, Alaska, but not hanging off a Time Warner cable.

Matt,

Thanks very much. I'll give TW another call, but I don't expect much. I get the feeling that I'm the only one with this particular problem. But I'm sure to follow up, and again thanks very much,
