SpamAssassin 3.4.2 has added support for HASHBLs through its
Mail::SpamAssassin::Plugin::HashBL plugin. To use the EBL with SpamAssassin 2.3.2 and later versions, you simply enable this plugin in your spamAssassin configuration. The SpamAssassin milter remains available for those using earlier versions of SpamAssassin.

The EBL has officially left beta and is now in production. Query volumes for the past three months have averaged between 200 and 350 million per day, a tenfold increase since last fall.
The nameservers that handle the public EBL zone
ebl.msbl.org have been changed to dedicated nameservers, due to the increase in query numbers. The new nameservers are unicast, not multicast, so response times will be somewhat slower than was previously the case, especially outside of North America and Europe. CloudNS is also blocking traffic from some locations that were sending extremely high volumes of inquiries, as we cannot afford to continue to serve sites that send high volumes of traffic from our free public mirrors.
High volume users such as ISPs should contact our reseller, SecurityZones, and arrange for commercial access to the EBL. Some educational and non-profit users will qualify for discounted or free access.

19 October 2016
The first project of the MSBL, the Email Blocklist (EBL), has entered beta testing.
The EBL contains cryptographic hashes of email addresses that appear in spam emails so that spam recipients can contact the spammer. Most listed email addresses are at large free webmail sites, and were originally spotted in the Reply-to headers or messsage bodies of "Nigerian" 419 Advance Fee Fraud spam or other types of spam that use similar techniques.
For more information, see EBL.
