The most common reasons for IP Addresses getting blacklisted are outbound spam and transmission of malicious files. When a rogue user or a compromised script sends out spam emails or transmits malicious files, the server IP gets blacklisted.
We have a zero tolerance policy against spam and have stringent protection in place to prevent spam outbreaks so that our IP Addresses do not get blacklisted.
We use MailChannels Outbound Spam Filter to strip out spam and malicious files before they leave our network. This helps keep our IP Addresses clean from getting blacklisted.
MailChannels Outbound Spam Filter is included for free with our Web Hosting, Reseller Hosting, and Semi Dedicated Hosting plans.
