About MultiRBL
MultiRBL checks an IPv4 or IPv6 address, or a domain name, against more than 200 DNS blacklists and whitelists at once. It also runs a forward-confirmed reverse DNS (FCrDNS) check, which many receiving mail servers expect to pass.
The site includes a Whois lookup, information pages about every list it checks, and a test by sending an email. Entries in the neutral lists are informational only. The site does not handle removal requests, so it suits mail administrators who can contact the list operators themselves.
