🚫 WPBL
WPBL, the Weighted Private Block List, shut down in 2024. What it used to check and why a historical listing no longer matters.
⚠️ Defunct since 2024
This blocklist shut down in 2024. The zone no longer lists anything and no mail server still queries it, so a historical listing has no effect on delivery. The page stays here for reference.

Weighted Private Block List
ℹ️ About This Blocklist
WPBL pooled complaint data from a set of participating mail servers and weighted each report by the reporter's reputation. The aggregate score decided who got listed. The service shut down in 2024, and the zone is now empty: it no longer lists any IP.
What a Listing Means
WPBL no longer operates, so nothing is listed here any more. Historically, a listing meant enough WPBL participants had flagged the IP that the weighted score crossed the threshold.
🔢 DNSBL Return Codes
When listed, the DNSBL returns one of these 127.x.x.x addresses. The specific code indicates the reason for the listing.
| Return IP | Meaning |
|---|---|
| 127.0.0.2 | Listed in WPBL (zone now defunct) |
ℹ️ Delisting
Nothing to do. WPBL shut down in 2024 and the removal form is gone. No mail server still queries it, so a historical WPBL listing has no effect on delivery.
