A blocklist (previously referred to as a blacklist) is a list of “items” that are considered as unsafe and therefore are denied access. A blocklist might consist of:
IP Addresses
Domain Names
Email Addresses
Short URLs
Drive URLs
Bitcoin Wallet Addresses
Attachment Hashes…
It is used to prevent the reception of spam, viruses, phishing, malware, and other email-borne threats.
Blocklists are used in various areas within security architecture, like; firewalls, DNS servers, directory servers, web proxies, authentication, and API gateways. While our blocklists are only designed for email servers.
Do you want to remove your IP/domain from one of our blocklists?
Please use our lookup-service and follow the instructions there in order to get that resolved.
