Spamhaus & SpamAssassin provide a simple alternative to expensive email filters

March 25, 2019 by Milly Fawcett

Virus Bulletin Spam Verified LogoIn recent independent tests Spamhaus’s block lists, used alongside a specially configured SpamAssassin, stopped 99.43%* of spam emails, with 0.02% false positives.  These results are similar to some of the more expensive email filter solutions on the market.  Perhaps it’s time to consider a more cost-effective & simple anti-spam solution?

Using Spamhaus’s block lists with SpamAssassin isn’t new, what’s changed?

Until recently those using SpamAssassin and Spamhaus’s block lists had to rely on the programme’s default configuration, or, manually change SpamAssassin’s configuration based on what the user believed to be the best settings.

Now, users no longer have to rely on intuition or the defaults: we have created the optimum settings.  At a high-level, the experts at Spamhaus have introduced new analysis for the headers and tweaked both the rules and weighted scoring.

With these changes, you can achieve similar results you would expect from a costly email filter product, all for the price of a subscription to Spamhaus’s Block lists via the Data Query Service(DQS), and the time taken to download the SpamAssassin add-on.

How do I get my hands on these recommended settings?

Firstly, it’s worth noting that this will only work for subscribers to the Spamhaus DQS. Additionally, you need access to all our block lists, i.e., Spamhaus’s Domain Policy Block List (DBL), Zero Reputation Domain (ZRD) and Spamhaus’s ZEN service, which includes the Spamhaus Block List (SBL), the Exploits Block List (XBL) and the Policy Block List (PBL).

With all the above in place just go to https://docs.spamhaustech.com/ and find ‘Data Query Service using SpamAssassin’ or click here, and download the instructions and Spamhaus’s SpamAssassin add-on. Naturally, if you are using a subprogram with SpamAssassin you will need to amend accordingly.

Effective email filters needn’t cost the earth, nor take excessive amounts of time to configure.  Download the config and sign up for a free 30-day DQS trial today, and see how simple it can be.

 

 

* The VBSpam results refer to the test configuration where Spamhaus’s data-sets were the only ones used: lookups to all other services supplying data were disabled. SpamAssassin users will further increase the effectiveness of this set-up by turning on services that deeply analyse mail contents such as the ClamAV open source anti-malware engine.
