Question

How do I create a listheader unsubsribe based on a typology rules?

I believe you are trying to use the typology rule to automatically add a list-unsubscribe header to the deliveries.

You can use this code to do that:

function addHeader(headers, header, value)  {
  
  var headerLine = header + ": " + value;
  var regExp = new RegExp(header + ":(.*)$", "i")
  var headerLines = headers.split("\n");
  for (var i=0; i < headerLines.length; i++) {
    var match = headerLines[i].match(regExp)
    if ( match != null ) {
      // replace the existing header line
      headerLines[i] = headerLine;
      return headerLines.join("\n");
    }
  }
  
  // add a new header line
  headerLines.push(headerLine);
  return headerLines.join("\n");
}

function getHeader(headers, header) {
  
  var regExp = new RegExp(header + ":(.*)$", "i")
  var headerLines = headers.split("\n");
  for each (line in headerLines) {
    var match = line.match(regExp)
    if ( match != null ) {
      return match[1].replace(/^\s*/, "");
    }
  }
  
  return "";
}

var header = getHeader(delivery.mailParameters.headers, "List-Unsubscribe");
if ( header == "" ) {
  // List-Unsubscribe header needs to be added
  delivery.mailParameters.headers = addHeader(delivery.mailParameters.headers, "List-Unsubscribe", "<mailto:<%@ include option='NmsEmail_DefaultErrorAddr' %>?subject=unsubscribe<%= escape(message.mimeMessageId) %>>");
}
else if ( header.match(/message\.mimeMessageId/) == null ) {
  // message ID need to be added for gmail
  header = header.replace(/subject=unsubscribe/, "subject=unsubscribe<%= escape(message.mimeMessageId) %>")
  delivery.mailParameters.headers = addHeader(delivery.mailParameters.headers, "List-Unsubscribe", header);
}

Hello @jkkkkkkkkkkkkkkkkk ,what you mean by listheader unsubscribe on typology rule? It is not clear at all. What I understand is to create warning if the template does not contain list-unsubscribe header? If that so in typology rules you have entire delivery object at hand and you can to check the headers of the message with eg regular expression  Marcel
