But nothing at 64.94.110.11 answers except the mail rejector:

I’ve heard tell that ISPs are filtering this IP, although I haven’t seen that yet… besides, that would result in timeouts, rather than a nearly immediate reject.

I give them another couple of days, and we will be rid of this. Even more, I hope this provokes an investigation into VeriSign’s business practices.
