Updating to version 11.1

,

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.
