EarthLink did not have infrastructure in place to do the mail relay for their own customers at the time of this supposed "opt in". I personnally did the modifications to the InterJet to support this, and they had no server names available to place in my input fields at the time the problems started. This resulted in a significant disruption in service for our installed customer base. Given what I have heard some people say about EarthLink since then, I sincerely question the correctness of your statements that the disruption in customer service was "voluntary".
