IMPORTANT UPDATE - November 2023

After 20 years of operation, this service will be shut down in 2024.

The blocklist no longer contains any entries; it's an empty list.

If you run a mail service and currently query our DNSBL or rsync feed, please stop querying the WPBL. The service will be completely shut down in 2024.

If you run a mail server, there is no action for you to take, because your IP address is not listed on the WPBL. The list contains no entries.

Querying the WPBL

The DNSBL can be queried under but will always return NXDOMAIN (non-existent) because the blocklist is empty. For now, the DNSBL continues to respond to queries, but we ask that everyone stops using the service.
