🚫 SPFBL
How SPFBL combines SPF validation with reputation data, and the delist flow on spfbl.net.
ℹ️ About This Blocklist
SPFBL is a Brazilian-origin DNSBL that mixes IP reputation, SPF validation results, and complaint data into a single score. Heavily used across Latin American mail infrastructure.
What a Listing Means
The IP's SPFBL score has slipped, either from a broken SPF chain on the sending domain or accumulated complaint data.
🔢 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 SPFBL |
✅ How to Request Delisting
Fix the SPF record on the sending domain first — SPFBL re-checks during delist. Then submit the removal through the SPFBL delist tool.
