New IMF Tune Build - Important DNSxL Updates

A new IMF Tune build is now available for download.

IMF Tune v7.1 build includes an important fix to the DNSxL functionality. We recommend all IMF Tune v7.x users to upgrade to the latest build.


Fixed DNSxL Processing Component

We identified a case where emails managed to bypass DNSxL processing. This may happen when spammers repeatedly send the same spam email. On encountering the email for the first time IMF Tune correctly applies DNSxL processing and caches the results.

On processing identical spam emails, a failure to correctly read the DNS cache could lead email processing to skip DNSxL filtering. The emails would still be processed by all other filtering stages but the final SCL rating would not comprise the DNSxL results.

This problem is now fixed and we encourage all IMF Tune users to upgrade.
