I mean this in the kindest way, and hope I am not suggesting something 
you've already tried, but I sent email with an explanation to 
support at and had success in removing an IP address for a 
mailing list that I manage. It got listed when we switched servers, 
because it went from zero emails to 800-900...

It took about 24 hours to get it straightened out.

Hope that helps.
