ℹ️ About This Blocklist

The Composite Blocking List flags IPs whose sending pattern looks automated: compromised machines trying to deliver spam, mail bots, malware. CBL was folded into the Spamhaus XBL. The old abuseat.org lookup now redirects to Spamhaus, and removal happens through the Spamhaus Blocklist Removal Center.

What a Listing Means

The IP is showing the fingerprint of a bot or an infected host: direct-to-MX delivery, unusual SMTP behaviour, or known malware traffic.

🔢 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 CBL: automated or bot-like sending pattern detected

✅ How to Request Delisting

CBL is now the Spamhaus XBL. Run the IP through the Spamhaus Blocklist Removal Center. The result usually names the specific malware family or behaviour. Clean the host, then submit the removal. Spamhaus re-tests before clearing the listing.
