What is RBL?

RBL (or DNSBL) is DNS based spam block list. It is a list of IP addresses and domain names that supposedly are source of email spam. Most mail servers and spam filtering systems use spam block lists. If your domain name or mail server IP address is in the spam list, email you send may be rejected or stuck in the spam folder. Blacklists that contain blacklisted domain names are often called URIBL.
