Insert a new SMTP addresses into an existing Header

Any Headers you wish to alter must be in the Matching Headers csv, or they will not be processed!

This example will alter the existing To address header, and will insert a new recipient into the To header:

Example: Adding a Delivered-To header if one is not present

Script

if(headerBeans.get("Delivered-To") == null) { 
 var hdr = jemhUtils.addPreProcHeader("Delivered-To", "yourmailbox@blah.com"); 
 headerBeans.put("Delivered-To", hdr); 
 print("created default Delivered-To: header : "+hdr.getUpdatedVal());
}
