ℹ️ About This Blocklist
Mailspike scores sending IPs on a reputation scale from L5 (worst) to H5 (excellent). The bl.mailspike.net zone combines its spam-wave list with every IP rated L3 or worse, so a listing here means either a live spam wave or a sustained bad reputation.
What a Listing Means
The IP is either participating in a spam wave right now, or its reputation has sat in the bottom three bands long enough to be published as a block recommendation.
🔢 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: spam wave participant |
| 127.0.0.10 | L5 reputation: worst possible |

✅ How to Request Delisting
Look the IP up on Mailspike and use the removal request on the result page. Reputation-driven listings clear as the score recovers, so fix the sending problem first or the score pulls the IP straight back in.
