Blacklist check

We have introduced a new Monitor Type: Blacklist. This Monitor will check if your server hostname and IP address is listed on 51 blacklists. These blacklists are mostly used to filter spam but you can imagine being listed on such a blacklist can hurt your search engine rankings and overall trustworthiness. Because blacklists do not change every minute, this monitor will check twice a day. If you are listed we will keep monitoring every hour until you have been removed from all backlists.

On the blacklist check page you can run a quick scan for your webserver of mail server.
