Implemeting the EBL
Before you configure your mailserver or spam filtering system to use the EBL, read the Purpose and Design pages, or download and read the EBL Blocklist information leaflet. These will provide details about the EBL that you will need to know before you set it up and use it.
Implementing the EBL on most mailservers requires an extension to existing MTA software or a filter. The following tools currently provide EBL support:
Mail::SpamAssassin::Plugin::HashBLplugin. To enable the EBL, simply enable this plugin in your SpamAssassin configuration. For earlier versions of SpamAssassin, a module is currently available and can be downloaded here. Consult the SpamAssassin documentation for instructions on installing a new module.
If you use Linux, you might also find Catherine Jefferson's dnslcheck.sh script useful. It takes an IP address, a domain, or an email address, and queries the specified blocklist or all blocklists. After you unpack and install it, type
dnslckeck.sh email@example.com to test the EBL. Type
dnslckeck.sh help for use information, and
dnslckeck.sh list for a list of supported blocklists.
Although the EBL is now in production, he EBL team welcomes contributors and user reviews, and continues to support tools development. For more information, contact the MSBL contributors team.
