About Blacklist Lookup

Scan an IP address through multiple DNS-based blacklists (DNSBL) and IP reputation services, to facilitate the detection of IP addresses involved in malware incidents and spamming activities. This service checks in real-time an IP address through more than 80 IP reputation and DNSBL services. This service is built with the IP Reputation API by APIVoid.

The Return Path Blocklist (RPBL) from Validity collects a number of email server IP addresses engaging in spam-like behavior and unsafe email practices. This blocklist is based on Validity’s robust data sources and cooperative industry partnerships, and is widely used by mailbox providers, security vendors, and filtering agencies as a contributing factor in their filtering algorithms and policies. 

Email administrators often do not know if their domain has been added to any of the major email blacklists. Only after issues start occurring are organizations made aware of blacklist issues. And by that time, it is already too late. The first consequence is that communications cannot be sent to users. If you are an email administrator and are concerned about the possibility of being blacklisted, try the Dotcom-Monitor continuous blacklist monitoring solution free for 30 days. With the Dotcom-Monitor DNSBL monitoring solution, you can set up email, SMS text message, or phone call alert notifications as soon as your domain or IP address is detected on a blacklist.
