Messaging Services Firm MxToolBox, Inc Adds Seven Blacklists to Blacklist Lookup Tool

MxToolBox, Inc. announced today that it has added six blacklists, also known as blocklists, RBLs, or DNSBLs, to its popular email blacklist lookup tool. The MxToolBox blacklist lookup tool will now check IP Addresses for listing on the MSRBL-Images, MSRBL-Phishing, MSRBL-Spam, MSRBL-Viruses, MSRBL-Combined and SpamHaus PBL blacklists, in addition to the 130 plus blacklists the tool currently checks.


The company added the lists to the tool to improve the quality of results for users. ?We constantly work to make sure we have the most valuable, up-to-date list of Blacklists available to our users,? Founding CEO Eric Rachal said. ?If there is a list that might cause deliverability problems for legitimate email users, we want to make sure that it is included it in our tool.?


Blacklists are lists of IP Addresses that have sent spam or have exploitable characteristics. Blacklists are commonly employed by email administrators to block incoming spam. There are dozens of blacklists available for use and each has a unique criteria for including an IP Address. For example, some lists include IP Addresses serving machines that are infected with worms and viruses, and others list IP Addresses within dynamic ranges. While blacklists certainly help fight spam, they can also block legitimate emails from non-spamming IP Addresses, an event referred to as a false positive.


The MxToolBox Blacklist Lookup tool is a free service that allows email administrators and users for non-spamming organizations who are having email deliverability problems to identify any blacklists that list their IP Addresses and see the reasons for the listing. The company also provides free blacklist consultations to companies who are listed or want to proactively avoid being listed. For non-spamming companies with blacklisted IP Addresses that cannot solve the problem, MxToolBox offers unique paid services to permanently eliminate the problem.


Joel Harvey, Director of Marketing explains, ?The blacklist tool is not about email blacklists as much as it is about email deliverability. That is what our tool and our services are designed to do?enable and ensure the delivery of legitimate, non-spam email. The first step is to find out that you have a problem, like a blacklisted IP. The next step is to find out why. You may have a virus, you may have some configuration issues, or you may have an IP Address in an un-trusted range. The final step is to take action so that your critical outbound email starts flowing again.?
