For many organisations and individuals email is a critical form of communication. We rely heavily on email being a uninterrupted and immediate form of communication. Unfortunately like many useful business and communication tools, email is often abused. Blacklists also known as DNSBL’s or RBL’s are one method often utilised to reduce the amount of unsolicited/Spam email reaching our inbox. Although extremely useful these blacklists are often prone to false positives, commonly rejecting legitimate communication, through the listing of IP’s belonging to legitimate mail servers and email providers. Listings can occur for a number of reasons, but when we rely on email so heavily the listing of legitimate mail servers can have devastating business and financial consequences.

There is a large number of Blacklist providers out there, utilised by a variety of different companies and email service providers. As not every email gateway uses the same blacklists to reject email it can be some time before the relevant admin is aware that communication is being disrupted.

The MX Lookups Blacklist monitor is designed to help limit disruption by providing notifications of your email server /providers IP addresses being listed on commonly used blacklists.
Once registered you can monitor an unlimited number of IP addresses for listings on common blacklists. Once you have added the IP or hostname to the monitor, MXLookups.com will proactively monitor the blacklist’s for listings. The status of your IP’s can be viewed within your account at anytime. In addition you will receive an email notification every 24 hours informing you of blacklist listing effecting you. Allowing you to take necessary action to de-list your IP addresses as required.

MXLookups.com currently provides this service free of charge. Simply create a free account and get started. If you have any questions please check the FAQ here or feel free to contact us through the form at the bottom of the page.
