This article describes how you can customize the templates for the design of the system emails of NoSpamProxy (including the PDF mails) starting with NoSpamProxy 11.x so that different designs are used based on the sender domain. NoSpamProxy uses the template engine for .NET “Razor” as basis for the dynamic change.

The CSHTML files to be edited are located in the directory %Program Files%\Net at Work Mail Gateway\Intranet Role\Templates. After the change, the files are automatically replicated to all connected gateway roles.

IMPORTANT
You need at least rudimentary HTML knowledge in order to make the adjustments.

Adaptation of the template files

You are welcome to request prefabricated sample files with different designs from NoSpamProxy Support. This file can only be used as of NoSpamProxy 11.0. In this example two different designs are used for the sender domains netatwork.de and nospamproxy.de. You can extend or reduce the number of domains at any time.

After downloading, unpack the ZIP file into a temporary folder. It contains the following files:

  • CommonMailTemplate.cshtml
  • CommonMailTemplateNaw.cshtml
  • CommonMailTemplateNsp.cshtml
  • ConvertMailContentToPdfAttachmentActionPdfHeader.cshtml
  • ConvertMailContentToPdfAttachmentActionTeaser.cshtml
  • EncryptedMailNotificationTemplate.cshtml

Start with the files that begin with “CommonMailTemplate”. Here you determine the appearance of all emails that are required for the PDF Mail. Make sure that you store the standard design in the CommonMailTemplate.cshtml. Customize the style sheets in the respective files according to your needs. The corresponding logos will also be included in these files. In later live operation, the logo files with the correct name must also be available in the Templates folder.

Then adjust the file “ConvertMailContentToPdfAttachmentActionPdfHeader.cshtml”. This file determines the layout of the PDF file as such. In contrast to the CommonMail template files, you only need one file here to define the exceptions. The adjustments take place in the upper part. An example for three different designs is included. What is important is that you specify the design for the different domains. If NoSpamProxy does not find the corresponding sender domain during live operation, it uses the default design, which you can define with the template editor in the admin GUI.

When all files are adjusted, copy all CSHTML files into the Templates folder of your program version. Make a backup of all contained files beforehand!
Please note that the files will be overwritten when patching or upgrading. After a version upgrade, please do not copy the older, modified files over the newer ones, but modify them again. Otherwise there is a risk that new, necessary information will be missing in the template files.
