Charter email addresses

[Bob]

For all of you who have Charter as your email service, every message I send to you comes back refused, at least that's what I get from charter.net, saying charter refused my email address.
I have sent charter numerous emails asking why they are blocking my address but they have never responded. I have 7 email addresses with knology.net and have tried more than one with the same result.
So if you have charter and have not received any emails from me, that is why. You should contact charter and ask why they are blocking knology.net email addresses.
