The realtime blacklist (RBL) is a database with IP addresses from which realtimeBLACKLIST.COM does not recommend the acceptance of e-mail.
The RBL is queriable in realtime by e-mail systems throughout the Internet, allowing mail server administrators to identify, tag or block incoming connections from IP addresses which realtimeBLACKLIST.COM deems to be involved in the sending, hosting or origination of Unsolicited Bulk Email. This RBL also lists IP addresses that are used in Botnet or for spreading malware/viruses. The RBL database is maintained by realtimeBLACKLIST.COM specialists and some of its sponsors that are located in the Netherlands.
