IP BLACKLIST CHECK

IP blacklist check

Check your outgoing mail server’s IPv4 address against SpamCop and PSBL. Enter a domain to check its web IP addresses.

Back to home

For email, enter your outgoing server’s IPv4 address. A domain checks up to two web A records; these may not be your mail server.

Enter an address to start.

This tool queries only the SpamCop and PSBL IPv4 lists. Not being listed does not guarantee a clean reputation everywhere or email delivery. Unavailable sources are marked inconclusive. Spamhaus is not included in this version.
