Hi @Asha Pathak ,

If your instance is set up to use your organization's own mail server or a hosted service such as Office 365, it's recommended to set up a rule (using whatever mail server software/service you're using) to add the custom header. If that's not possible, or if you're using the ServiceNow mail infrastructure (the default option) you can use a Business Rule to insert the custom header (tested working on Madrid):

Create a Business Rule:

• Name: "Add Custom Email Headers" (can be whatever you like)
• When to run: before
  
  • Insert ticked
  • Update ticked
• Order: 100
• Advanced
  
  • Use the following script as an example (replace "X-MyCustomHeader" with the name of the header and current.instance with the variable or literal value that you want in the header:

    (function executeRule(current, previous /*null when async*/) {
    
        if(current.headers.indexOf("X-MyCustomHeader") < 0){
            current.headers = "X-MyCustomHeader:" + current.instance + "\n" + current.headers;
        }
    
    })(current, previous);

Hi @Asha Pathak ,

How did you set it on Prod directly?

[Asha Pathak]

@Community Alums Yes we have to set it to directly prod, and the configuration is not on dev and test instance
