  • Public DNS disabled

    March 1, 2009

    As of 1 March 2009, public DNS of individual lists such as sc.surbl.org is disabled. Please use multi.surbl.org instead. multi includes all of the individual lists, so the individual lists are obsolete. SpamAssassin 3.0 and later queries multi by default, so it does not need any changes. If you are using SpamAssassin 2.6, then plesae upgrade to version 3 or later.


SURBL Data Feed Request

SURBL Data Feeds offer higher performance for professional users through faster updates and resulting fresher data. Freshness matters since the threat behavior is often highly dynamic, so Data Feed users can expect higher detection rates and lower false negatives.

The main data set is available in different formats:

Rsync and DNS are typically used for mail filtering and RPZ for web filtering. High-volume systems and non-filter uses such as security research should use rsync.

For more information, please contact your SURBL reseller or see the references in Links.
