About Blacklist Lookup

This software compares an email server's IP address against more than a hundred DNS-based email blacklists to evaluate its legitimacy. If your mail server is on a blacklist, your messages may never reach their recipients. The widespread usage of "blacklists" is the most common method for combating spam email. MX If you ever find yourself in a situation where you need to send an email but don't know the server's address, you may start by looking it up on Lookup. After a long period of inactivity, an IP address may be removed. When this happens, both outgoing and incoming emails will fail to be processed, and the error message "this site can't be reached by the backlist ip" will be shown. You are provided with a basic SEO analysis tool to help you evaluate the site as it is right now. Enter the URL you wish to search, and the tool will return a list of results from the database servers with the press of a button.
