We have released the Version 13.0.19169.1943 on July 09th, 2019. This Version is an upgrade release where the following Bugs are fixed and new features are added or changed.

Important Information

As of upgrade version 12.2.18253.1152, a script for cleaning up the message tracking is included- This script deletes orphaned entries in the database. This may cause the setup not to respond for a some time. The setup must not be aborted and must run until completed. Please schedule a longer upgrade period for this.

If the Protection module is licensed, it is possible that the Cyren services do not work and no viruses and spam checks are performed after the update to version 13, although the NoSpamProxy license itself has been correctly validated. To correct this, in the NoSpamProxy Management Console go to Configuration/NoSpamProxy Components/Gateway Roles, select the gateway role(s) and click on Synchronize configuration.

Synchronize configuration

It is possible in combination with some Domain names, that the Reputation filter will block emails due to an obfuscated owned Domain. Only in this case we will recommend to reduce the SCL Points to maximum 2 SCL Points (Default is 4 SCL Points) for the test ‘Header-From’ is an owned Domain at the Reputation filter, to be found on the tab Filters at the applied rule, on tab ‘Header-From’ Tests. This will be improved within the next Major Version.
Example: Owned Domain = example.com, but the Reputation filter will also detect my-example.com as an obfuscated owned Domain.
