Reputation & Blacklist Monitor

Stay off the DNSBLs. Stay in business.

What it checks

We continuously query 12 major DNS-based blacklists for any IP or domain you monitor:

Provider	Zone	Type
Spamhaus ZEN	`zen.spamhaus.org`	IP
Spamhaus DBL	`dbl.spamhaus.org`	Domain
Barracuda	`b.barracudacentral.org`	IP
SORBS	`dnsbl.sorbs.net`	IP
SpamCop	`bl.spamcop.net`	IP
UCEPROTECT L1	`dnsbl-1.uceprotect.net`	IP
SURBL	`multi.surbl.org`	Domain
PSBL	`psbl.surriel.com`	IP
CBL Abuseat	`cbl.abuseat.org`	IP
Mailspike	`bl.mailspike.net`	IP
Spam Eating Monkey	`bl.spameatingmonkey.net`	IP
WPBL	`db.wpbl.info`	IP

Reputation score

Each check produces a 0–100 reputation score:

score = (clean_listings / total_responding_listings) × 100

Score	Meaning
95–100	Excellent reputation
80–94	Healthy, monitor for changes
0–79	Listed somewhere — investigate immediately

How to use it

Continuous monitoring

Go to Security → Blacklist
Click Add Monitor, enter an IP (8.8.8.8) or domain (example.com)
Choose frequency: hourly / daily / weekly

Instant check
