Black List Directory

  • Relay Database (ORDB) - http://www.ordb.org/
    A validated database of mail servers that permit third-party relay. Also in Francais, Nederlands and Dansk.
  • Composit Blocking List (CBL) - http://cbl.abuseat.org/
    The CBL is a DNSBL which takes its source data from very large spamtraps, and lists IPs of open proxies and worms/viruses.
  • OpenRBL DNS Lookup - http://openrbl.org/
    Enter an IP address or a hostname to find out which blacklists (if any) list it.
  • Drbcheck: Dr. Jorgen Mash's DNS Database List Checker - http://moensted.dk/spam/
    Lists all DNSbl's (RBL's) and enables users to make a query against all the lists.
  • MAPS Realtime Blackhole List (RBL) - http://mail-abuse.org/rbl/
    Lists email sites which have refused to limit their relaying, leaving the potential for their use as spam gateways.
  • Relays.visi.com - http://relays.visi.com/
    Blacklist of open relaying mail servers that have recently transmitted spam.
  • Distributed Server Boycott List (DSBL.org) - http://www.dsbl.org/
    This list contains email servers which are non-secure and potentially servers with dumb and/or malicious users. It is purely composed of data DSBL receives; DSBL should never send out data by itself.
  • Spamhaus Block List (SBL) - http://www.spamhaus.org/sbl/
    All IPs on the SBL belong to known spammers, spam gangs, or spam support services. The SBL includes IPs from both the ROKSO database and IPs of spam services listed in the Spamhaus database.
  • Mail Abuse Prevention System - http://mail-abuse.org/
    MAPS aims to defend the Internet from spammers by educating ISPs and providing real time blocking lists of known spam sources.
  • The Spamhaus Project Register of Known Spam Operations (ROKSO) - http://www.spamhaus.org/rokso/
    The Spamhaus Project's Register Of Known Spam Operations (ROKSO) Database. ROKSO collates evidence on known hard-line spam outfits that have been thrown off Internet Service Providers over three times.
  • Spam Prevention Early Warning System (SPEWS) - http://www.spews.org/
    SPEWS maintains a list of known spam sources and spam friendly hosts so that e-mail can be rejected from these problem sites.
  • rfc-ignorant.org - http://www.rfc-ignorant.org/
    The home for domains who don't play by the rules. A number of lists (at present "dsn", "abuse", "postmaster", "whois" and "ipwhois") which contain domains or IP networks whose administrators choose not to obey the RFC's, the building block "rules" of the net.
  • SpamCop - Blocking List Information - http://spamcop.net/bl.shtml
    This list contains IP addresses which have been reported to SpamCop as carriers of spam (source of e-mail or verified, open relay). Some of these reports now come from spamtraps (email addresses used strictly to receive spam).
  • MAPS Relay Spam Stopper (RSS) - http://work-rss.mail-abuse.org/rss/index.html The RSS is a list of email relays which have been used to send spam, for use in blocking spam by blocking mail which have gone through those sites.
