Upgrading from version 12.2 and earlier versions

Please install version 13.1.19330.1217 or higher before upgrading to version 13.2. You can download this version here.
Please also note all upgrade articles for older versions in our Knowledge Base under “Update Information”.

Upgrade NoSpamProxy

When upgrading from version 13.1 to version 13.2, all settings and user information are retained. Only the proxy settings and content adjustments of the template files (templates) must be saved as usual and reinstalled after the upgrade. This procedure is described under General update information.
For security reasons, please export existing DKIM keys from the console under “People and identities > DKIM Keys” BEFORE upgrading.

Additionally, please check the following points after the upgrade:

  • Content filter: As there have been changes to the file types (MIME Types), please check all content filters and their content filter entries
  • The reputation filter in the rule set has been extended in version 13.2 compared to version 13.1. This modification enables further, additional checks
    • Four additional checks on the HEADER-FROM
    • One additional check whether the transmission was secured with TLS
  • Starting with version 13.2, the incident to the Spam URI Realtime Blocklists is converted from an error to a warning

  • Calculation of the license values for the Encryption and Large Files modules has been changed. From now on inbound and outbound emails are considered. See License management in version 13 and higher.

    From version 13.2.20258.1435 a notification is displayed at the NoSpamProxy console start page that the client is no longer supported from version 14. All users who still have such a client active must not upgrade to version 14 until the migration on Microsoft side has been made. Further information is available here:

License type change

As of version 13.0 we have changed the integration of the license from license file to license key. This change is done automatically and no further action is required.
In case of problems, please refer to the Knowledge Base article How to install a new license.

Outlook Add-In

The upgrade of the gateway and the Web Portal necessarily requires an upgrade of the Outlook Add-In as well, otherwise communication with the Web Portal is no longer possible.
