Please follow the instructions in the installation manual and the general update instructions here in the Knowledge Base.

Before updating make sure to install .NET Framework version 4.7.2 and SQL Server version 2008 R2 or later.

Important note for update version 12.2.18253.1152 and later

As of version 12.2.18253.1152 (Fast Channel), a script for cleaning up message tracking is included. This script deletes orphaned entries in the database. It causes an increased disk space requirement on the drive with the database NoSpamProxyAddressSynchronization (Intranet roles database). Please check beforehand if there is at least five times as much storage space available on the drive as the current database.

The database file can be found in the installation folder of the Microsoft SQL Server. The default directory is “C:\Program Files\Microsoft SQL Server\<<<SQL Version.SQL Instance>>MSSQL\DATA\”.

This may also result in the setup not responding for a long time. The setup must not be aborted and must run until it is completed. Please allow a longer update period for this.

Upgrade from version 11.1

When updating from version 11.1 to version 12.2, consider the Knowledge Base article “What to consider when updating to version 12”.

Upgrade NSP

When updating from version 12.x to version 12.2, all settings and user information are retained. Only the proxy settings and content adjustments of the template files must be saved as usual and reinstalled after the update. This procedure is described in the general update notes.

Outlook Add-In

The update of the gateway and the Web Portal also requires an update of the Outlook Add-In; otherwise the communication with the Web Portal is no longer possible.

Updating from version 12.0

Please pay attention to the notes in the installation manual and the general update notes here in the Knowledge Base.

Before updating make sure that .NET Framework 4.6.2 or later is installed and the SQL Server version corresponds to at least 2008 R2.

Upgrade NSP

When updating from version 12.0 to version 12.1, all settings and user information are retained. Only the proxy settings and content adjustments of the template files must be saved as usual and reinstalled after the update. This procedure is described in the general update notes.

Outlook Add-In

The update of the gateway and the Web Portal also requires an update of the Outlook Add-In; otherwise the communication with the Web Portal is no longer possible.

Updating from version 11.1

Please pay attention to the notes in the installation manual and the general update notes here in the Knowledge Base.

Before updating make sure that .NET Framework 4.6.2 or later is installed and the SQL Server version corresponds to at least 2008 R2.

Upgrade NSP

When updating from version 11.1 to version 12.1, all settings and user information are retained during the update, with one small exception. Only the proxy settings and content adjustments of the template files have to be saved as usual and reinstalled after the update. This procedure is described in the general update notes.

Upgrading the content filter settings

The settings made so far for the content filters are fully adopted and converted to the new format. For this, the actions configured in 11.1 are migrated to the new “Content filter actions” and then linked in the content filters. The new actions have the function in their name so that they are easy to identify. Please check the correct configuration after the successful setup.

There is now an option to distinguish between an SMTP action and a Web Portal action. This makes it possible to distinguish whether a file attached to an SMTP email arrives at the NoSpamProxy gateway or is to be sent directly via the Web Portal. After the update, only SMTP actions are available. As long as nothing else is configured, the same settings apply to attachments that arrive via the Web Portal.

Note: Content filtering can be switched on/off on a rule basis in the rule settings on the “General” tab. If no content filter is configured and in use, this should be set to off.

Upgrading message tracking

The format of message tracking in the database has changed fundamentally. Only after the successful update to version 12.1, the Intranet role will migrate the old data into the new format. This means that the message tracking data created before the update will only be available about 15 minutes after the update. This time varies strongly and depends essentially on the available data and the load capacity of the machine. If the migration fails, a warning is displayed on the initial page.

New “Reputation Filter” Filter

NoSpamProxy 12.1 introduces the reputation filter for the first time. This new system has a total of 9 different checks, all of which focus on the origin of the email. After the update to version 12.1 this filter is not activated. Please add the “Reputation filter” filter manually to your ruleset and ideally adopt the pre-set values.

Outlook Add-In

The update of the gateway and the web portal also requires an update of the Outlook Add-In, because otherwise the communication with the web portal is no longer possible.

NoSpamProxy Management Console

As of version 12.1, it is necessary to additionally enable port 6061/HTTPS on the intranet role for the access of the management console from another system.

From version 11.0

SQL Server 2005 and 2008

Please check the SQL version you are using before upgrading. If Microsoft SQL 2005 or 2008 is still in use, an update to at least SQL 2008 R2, preferably SQL 2014, must be carried out before installing version 11.1. Before the SQL upgrade, stop the NoSpamProxy services in the Windows services to stop the database access. When upgrading, make sure that the bit version matches. SQL 2005 was typically installed in 32-bit.

You can get SQL 2014 Express here: https://www.microsoft.com/de-de/download/details.aspx?id=42299

Upgrade NSP

Please always follow the instructions in the installation manual!

When updating from version 11 to version 11.1, all settings and user information are retained during the update with one exception. The following manual activities must be carried out after the update:

If you have used the “Reverse DNS Check” action, you must reactivate it after the update. You will now find this function on the “Filter” tab.

Furthermore, you should check the completeness of the content filters for security reasons.

From version 10.1

When updating from version 10.1 to version 11.1, all settings and user information are retained during the update.
The group “NoSpamProxy Disclaimer Administrators” is added to use the NoSpamProxy function disclaimer. Please add all users who should manage the templates and rules of the disclaimers to this user group. After upgrading to version 11.1 please check the instructions on the start page in NoSpamProxy and follow the instructions.

Best Practices

If you do not use the Web Portal, please skip this point:

  1. Update all web portals first. The order is not important.
  2. Update all Gateway Roles that are not installed on the same system as the Intranet Role.
  3. Update the system with the Intranet Role last.

Email templates

The templates for automatically created emails are overwritten and should be saved beforehand to be on the safe side. With the new template system you can now make your graphical adjustments directly in the NoSpamProxy interface under “Preferences”. These settings will be kept for future updates or upgrades.

From Version 10

When updating from version 10 to version 10.1, all settings and user information are retained during the update.

From Version 9.2

When updating from version 9.2 to version 10.1, please note the following points.

Automatic user import

The import of ‘Active users’ has been changed to ‘Import all users as active’. This changed the behavior to match the current usage of user accounts in Microsoft Exchange Server.

Actions in rules

The action ‘Manage attachments’ was moved to the ‘Content filter’. The previous settings of the action will be lost and must be reconfigured after the update. The content filter can now manage file names, file types and sizes up to the user level. The configuration is done through the corporate users and the partners. The content filter is described in detail in the user manual.

Email flow in the rules

A rule with a email flow from a ‘corporate email address’ to a ‘corporate email address’ is disabled by the setup. This rule is no longer necessary from version 10, since the function previously covered by this rule is now covered by the default behavior of NoSpamProxy. Please check your rule set and adjust it if necessary.

Improved out-of-office response recognition

For automatic replies from your email server, such as out-of-office replies, you do not need an extra rule from version 10. NoSpamProxy automatically detects if a reply was sent from a company email server and assigns it to the appropriate rule for outbound email traffic.

Email templates

The templates for automatically created emails are overwritten and must be saved beforehand. After installation, you must apply the changes you made to the old templates to the new templates again. Further information is available in the article How to change the Web Portal Design for Version 10 and How to change NoSpamProxy notifications.

Changed behavior for accepting a sender with its own domain

Up to version 9.2 it was possible to allow external senders to use their own email domain via a rule. This is no longer possible. Email servers that want to use your sender domain must now be included in the list of ” corporate email servers “.

If the server cannot be specified, it is also possible to allow each server to use a specific sender address of your domain. However, this increases the risk of fake mails and should only be used as a “last resort”.

From version 9.0

When updating from version 9.0 to version 9.1 or 9.2, all settings and user information are retained during the update.

From version 8.5

When upgrading to version 9.0, the subdivision into the new areas Monitoring, People and Identities and Configuration is immediately noticeable. For each of these areas, users can be explicitly allowed access via security groups. This means that you can assign the rights to a person in your company, e.g. to only use the Monitoring area. This person would then have no access to People and Identities or Configuration. The installation program of the Net at Work Mail Gateway automatically makes the user logged on during the installation a member of all three groups.

The security groups mentioned above are explained in more detail below.

Mail Gateway Monitoring Administrators

Members of this user group may use the Monitoring area. This area displays email statistics, email queues, or key figures about the performance of your server.

Mail Gateway People and Identities Administrators

Members of this user group may use the People and Identities area. This area manages internal and external communication partners and their cryptographic keys.

Mail Gateway Configuration Administrators

Members of this user group may use the Configuration area. This area contains the settings of the Net at Work Mail Gateway and its gateway roles, such as connectors, rules, notifications, and connections to other systems.

The new structure consistently combines previously redundant configuration settings and enables task-oriented administration. This means that the management console of version 9.0 no longer focuses on the roles of the Net at Work Mail Gateway, but on the task you have to perform.

This allowed many areas to be merged and simplified. An example: The address rewriting area of version 8.5 had to be configured to match the local users and their email addresses. The address transcriptions have now been moved to the email addresses of the local users, so that the assignment between email addresses and address transcriptions is made automatically.

Finally, the Commtouch service has been renamed to CYREN. CYREN continues to provide you with a high level of service.

Warning
An upgrade to version 9.0 is currently only supported by version 8.5.

Some changes of version 9.0 have a strong effect on the installation of the update. This is the replication of all configuration data between the intranet role and the connected gateway roles. In particular, installations with more than one gateway role must be updated to version 9.0 with great care.

Furthermore, the roles “Reporting Role” and “UserManagement Role” have been combined and are now managed as “Intranet Role”. The new Intranet role will continue to work with the previous database of the UserManagement role. This database will be extended by the update by the tables of the previous reporting role.

In the previous versions, a separate certificate with the name of the service was created for each service and used for the connection between the individual roles. Since version 9.0, a certificate with the server name is created in the CN.

Please note
If you use a custom MSC file instead of the Management Console (MSC file) shortcut created by Setup, this file may not work after the upgrade and the interface may display errors. In this case, please delete your custom MSC file and recreate it.

From version 8.0

When updating from version 8.0 to version 8.5, all settings and user information are retained during the update.
