Domain Naming Server Blacklisting, better known as DNS Blacklisting, was designed as a beneficial tool to protect internet users from spam emails. Although the intention was to prevent spam and provide security benefits, it has become disruptive to innocent users.  How is this possible?  An individual’s mail servers can send volumes of junk mail, which in many cases are generated through a server that has been configured and used by spammers.  Unfortunately, once you are tagged as a spammer, the IP address of your server is added to the DNS blacklist by third parties.  Being added to the blacklist will prevent the sending and receiving of spam; however, it could potentially lead to the non-delivery of critical emails.  The hassle of being removed from these blacklists is a long and complex process.

Fortunately for those individuals who have experienced this in the past or those who desire to prevent this from ever occurring in the future, there are new cutting edge technologies that will reduce significantly and/or eliminate this from becoming an issue.  There are software as well as hardware solutions.  Software solutions have more flexibility and availability and would be the more cost friendly option.  Available hardware solutions are network devices that sit on the network and manage themselves, but tend to be a little more costly than software solutions. Both of these solutions offer great benefit and inquiring about the specifics may help you choose which one works best for you.
