Well its not really blacklisted. I check the IP from a website that can check if blacklisted and seems it is. And when I send to hotmail emails I get bounce but for others like gmail and yahoo it went ok but in spam folder.
I have interest in this. I need cost of the servers. I am thinking sending 100,000 for day. and i want to know how we can manage the ips, do you have setup the system for work with rotating ips if them get blacklisted?
