Our Blacklist Checker doesn't query this list
Spamhaus runs this zone, and it refuses lookups that come from shared hosting or public resolvers. Its free query service is for non-commercial users only. A check from our server would come back refused, or read clean when it isn't. Look the address or domain up at check.spamhaus.org instead. The listing details and return codes below still apply.
IP Blocklist (RBL)
cbl.abuseat.org
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.
