Spam blacklist (RBL, DNSBL) 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 listed in the spam list, email you send may be rejected or marked as spam.
