Support for DNSBL

We are now supporting the DNSBL with a local rsync feed.

To use this DNSBL refer to the scoring rule “RCVD_IN_UNSUBSCORE” in SpamAssassin (recommended) or add “” to your DNSBL configuration in the account control center.

UPDATE: We saw a handful of false positives within the first 48 hours of our own testing, so we’re just going to recommend using this one for scoring. We have added a new SpamAssassin test called “RCVD_IN_UNSUBSCORE” for it. The default score is 0.5 points.

Utilizing the world’s largest unsubscribe intelligence database, LashBack’s Unsubscribe Blacklist (UBL) empowers your organization to identify and block the very worst unsubscribe abusers; those that send email to addresses which have been harvested from suppression lists.
