On March 22nd I was notified by MX Toolbox that my server ip was blacklisted by ivmSIP and Hostkarma Black. I was aware of an attack some of our clients sites had suffered towards the end of January but we immediately took those sites offline and advanced security. So, I was surprised to find we were blacklisted.
I emailed both of the Blacklist companies explaining what had happened and what action we took. Hostkarma removed us immediately but ivmSIP has totally ignored all 7 emails I have sent to them over the past 8 days.
I have the impression that I need to accept their offer to sign up and pay a monthly fee to get removed. Is that the answer to resolve?
My question is, can anybody tell me what I can do to get these guys to de-list my ip? Obviously sending detailed emails explaining everything is of no use and I have no idea if they have even been read.
Any suggestions would be greatly appreciated.
Thank you Bryan
