What is DNSBL?

DNSBL, also known as a DNS blacklist, is a mechanism used to prevent email spam and other forms of online abuse. It works by maintaining a list of IP addresses or domain names that are known to be sources of spam or malicious activity. When an email server receives a message from an IP address listed on a DNSBL, it can choose to reject or flag the message as spam, helping to reduce unwanted emails and potential security threats.

Other Names of DNSBL:

• DNS RBL (Real-time Blackhole List)
• Blacklist
• BlockList
• Anti-Spam DNS Blacklist
