Critical Update to MDaemon AntiVirus/AntiSpam Engine (MDaemon AntiVirus/AntiSpam licensed feature)

Updated September 26, 2023

Summary
This update addresses the following critical issue for MDaemon users:

Re-integration of Outbreak Protection (Recurrent Pattern Detection). Cyren's proprietary Outbreak Protection service was previously removed as a result of Cyren's insolvency and exit from the industry. That technology has been acquired by a new provider and is now re-licensed and integrated for use in MDaemon Email Server.

Affected Customers
Customers using the optional MDaemon AntiVirus/AntiSpam licensed feature must upgrade to the latest version of MDaemon Email Server for which they are licensed or using (from the list below) to ensure access to the latest variant of Malware Detection (antivirus engine) and the new Outbreak Protection (antispam). Older variants of these products may cease to function without notice. Additionally, it is highly recommended that all MDaemon Email Server customers upgrade to a current eligible version* (from the list below) to receive the latest security and software features.

Affected Software
The supported versions listed below have been tested and determined to be affected. We recommend that administrators download the appropriate version and language file listed below.

There are no known issues that customers may experience when downloading the update.

* Critical update upgrades are free for all users. Customers must download the software version file for which they are eligible (the paid version in use whether the license is current or expired). If a different/ineligible version is downloaded, that version will cease to work after 30 days. MDaemon Technologies recommends using the most current version available to receive the latest security and software features. Renew or Upgrade your license here.
