Reason for Blacklisting of your IP address

There could be a 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 viruses or malware. Hosting a domain or website in a shared environment means that your IP address is the 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 domain on the server might have trouble with spam or malware. Most Internet service providers (ISPs) and web servers lookout for lists for IP addresses linked to computers that send out spam emails or unwanted activity.

Blacklisting happens when the volume of emails comes from a single server having spam or malware characteristics. At one point in time, the IP address of that particular server is flagged and blocked. The best way to whitelist IP address in your server firewall is to use ConfigServe Firewall (CSF) which allows you to manually whitelist your server IP address. CSF is considered s one of the most advanced firewalls owing to its numerous configuration options as compared to other firewalls. There are other firewalls that use “server IP whitelist” option But CSF allows to whitelist IP addresses very easily. Windows server or Linux server both follows the same approach for whitelisting IP address because CSF firewall is a standalone firewall that can run on both platforms.
