Share Article

In the latest round of the Virus Bulletin comparative testing of leading anti-spam solutions, the Spamhaus ZEN+DBL DNS Block List solution achieved a very impressive catch rate of 98.92% of all possible spam emails. Perhaps even more impressive is the fact that it did not block a single legitimate message or any newsletters which are included in the test to validate the quality of the filtering mechanisms used.

We estimate that Spamhaus blocklists are used to protected over 1.4 billion mailboxes on a global basis

The test ran for 19 consecutive days, and contained 176,485 emails, 171,963 of which were spam. Of these, 87,462 were provided by Project Honey Pot and 84,501 were provided by Abusix; they were all relayed in real time, as were the 4,315 legitimate emails. The remaining 207 emails made up a small corpus of newsletters which was generated by manually subscribing to a large number of newsletters, in a number of different languages and topics.
