A constantly updated list of hosts sending [Email] you may wish to reject. Originally created to list open relays abused to send [Spam], there are now various [RBL]s which also blacklist hosts for reasons such as being an open [Proxy], sending [Spam] directly, or having political views that oppose your own. |

[RBL]s are usually queried via [DNS], by looking up <tt>''ip''.rbl.example.com</tt>. Lookups for blacklisted hosts return an A record (usually for 127.0.0.2) and/or a TXT record (explaining why the host is blacklisted). |

[MailServer]s can be configured to check [RBL]s to determine whether they should accept an incoming [SMTP] connection. Most people subscribe to multiple [RBL]s. |
