System Requirements

Update Information 11.1, 12.x, 13.x

This article provides an overview of the minimum requirements that must be met in order to run NoSpamProxy.

Note: In order for you to receive support services,

  • the listed requirements must be fulfilled and
  • a corresponding manufacturer support contract must be in effect.

We do not guarantee the completeness of the following information on third-party products. In any case, make sure to check the manufacturer’s pages for updates!

General requirements

  • A corporate email server, either in the company network or in the cloud.
  • NoSpamProxy can NOT be operated using the combination “Domain Controller + Exchange + NoSpamProxy” on one single system, because the operation of Exchange on a domain controller is prohibited. See Exchange Server Supportability Matrix.
  • NoSpamProxy can be installed on a system in parallel with the email server. However, this combination is not recommended, because of duplicate port assignments (mostly ports 25, 443 and 6060/6061), which can cause problems during operation. We recommend to always change the ports of the email server in case of parallel operation, so that NoSpamProxy can be reached from outside via the standard ports.

NoSpamProxy uses the following standard ports:

  • Port 6060/6061 TCP
    • internal communication between the Intranet Role and the Gateway Roles
  • Port 25 TCP
    • SMTP
    • inbound and outbound
    • modifyable
    • also used by Exchange during parallel operation
  • Port 443 TCP
    • SSL
    • internal and external communication with the Web Portal
    • modifyable
  • Port 443 UDP
    • internal and external communication with the Web Portal
    • only necessary if QUIC for HTTP/3 should be used
  • Port 465 TCP
    • POP3
    • to retrieve POP3 messages
    • no support for NoSpamProxy Protection

Hardware requirements

The following specifications are minimum requirements. The recommended configuration depends on the email volume and the use of individual NoSpamProxy functions.

  • 4GB RAM
  • 2 processor cores
    • virtualized or physical
  • Hard disk space
    • should be discussed individually with the support or presales team
    • If Intranet and Gateway Role are operated on one single system with no Web Portal present, 100GB should be sufficient.

Supported NoSpamProxy versions

The following versions are currently covered by our support:

  • Version 13.2
  • Version 13.1
  • Version 13.0
  • Version 12.2
  • Version 12.1 (no longer supported with release of version 14)

Visual Studio Tools for Office 2010 Runtime or higher is required to install the Outlook Add-In.

Further notes

  • When using the NoSpamProxy Management Console on a Windows Server 2012 R2, it may happen that the console start page does not display the Latest News. The reason for this is that the operating system cannot open a secure connection to the source of the messages. For this, the following two TLS ciphers must be activated in the operating system, followed by a restart of the operating system
    • TLS_DHE_RSA_WITH_AES_256_GCM_SHE384
    • TLS_DHE_RSA_WITH_AES_128_GCM_SHE256
      For more information visit https://support.microsoft.com/de-de/topic/update-f%C3%BCgt-neue-tls-cipher-suites-und-chiffre-suite-priorit%C3%A4ten-in-windows-8-1-und-windows-server-2012-r2-ge%C3%A4ndert-8e395e43-c8ef-27d8-b60c-0fc57d526d94
  • Make sure that any third-party applications you use that connect to NoSpamProxy are covered by their respective manufacturer’s support. If this is not the case, the NoSpamProxy support team will not be able to provide support.
  • Make sure that the necessary exceptions are set in the local Windows Defender (and other AV scanners used) to allow NoSpamProxy to run smoothly.
  • If you have installed NoSpamProxy and Microsoft Exchange on the same server, make sure that the respective version of the framework is supported by Exchange before installing or updating the Microsoft .NET framework. An overview of supported versions is provided in the Exchange Server Supportability Matrix.
  • Further details about the installation of the add-in can be found in the Outlook Add-In Installation and Group Policy manual. There, the installation with the MSI file for software distributions is also addressed.

Updating to version 11.1

Update Information 11.1, closed

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.

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.
