Verify IP reputation against global anti-spam databases
Querying global DNSBL servers...
DNS-based Blackhole Lists (DNSBL) are real-time databases that track IP addresses sending spam, hosting malware, or acting as open proxies. Email providers like Gmail and Outlook query these lists to decide whether to accept your emails or send them to the Spam folder.
If your office IP or mail server IP is blacklisted, your business communications can come to a halt. Regular monitoring ensures you can catch reputation issues early and request delisting before it affects your operations.
