There could be couple of reasons that might have caused your domain/IP address to be blacklisted. It could be due to the violation of ICAN-SPAM regulations or incursion of virus or malware. Hosting a domain or website on shared environment means that your IP address is same as the IP address associated with several other domains sharing the same server. In such a situation, blacklisting happens more frequently as one other domains on the server might have trouble with spam or malware. Most Internet service providers (ISPs) and web servers look out for lists for IP addresses linked to computers that send out spam mails or unwanted activity.
Procedure of whitelisting your IP
Blacklisting happens when volume of mails come from a single server having spam or malware characteristics. At one point of time the IP address of that particular server is flagged and blocked.
