End of Life of old versions of spamBlocker engine
Important spamBlocker Update
In June 2020, WatchGuard released a new version of Fireware that provided an updated spamBlocker engine which uses Cloudmark technology to replace the old Cyren engine. Response has been very positive and many customers and partners report significantly improved detection rates and fewer false positives after they upgraded to Fireware v12.5.4 or higher. We are now announcing that the old Cyren engine will be retired later this year.
