How do I check if I have correctly configured my email server to use your DNSBLs?
The Blocklist Tester (BLT) is quick and easy to use, helping you ensure your setup is correct. It sends a series of test emails to your specified email address. If your server is correctly set up to query our blocklists, all the emails should be rejected. The BLT provides a summary of precisely what emails have been rejected or delivered.
