Blacklist Lookup Tool

This test will check a mail server IP address against a large number of RBL’s, DNSBL or Blacklists. If your server is listed on any of the Blacklists you will be notified in the blacklist lookup results. You may enter 1 or more IP addresses separated by spaces or newline. Single lookups are fast however checking a large number of IP’s against the large number of blacklists may take a little time. Be patient!
If your not sure of what mail server you should be checking the blacklist for, try our MX Lookup tool
