Drop an email that has a Precedence header when using a Profile Group

1 Summary
2 Work-around Example Script

Summary

In a single Profile, when a incoming email matches a Project Mapping that has Message Filter Action set to ignore(drop), JEMH will Drop the email. However, when using a Profile Group, JEMH will try and find another matching Project Mapping that allow emails with a Precedence header to create Issues.

A work-around to make the Profile Group drop the email and stop checking for other Project Mappings when Precedence: bulk is present will require a Script Field Processor.

Work-around Example Script

This Script will be placed on the specific Profile with the Project Mappings that want to ignore(drop) emails with a Precedence header. The Script consists of three sections:

An array is needed to store the catch email addresses of Project Mappings that do not want to process emails with a Precedence header. These Addresses will need to be entered into the array manually.
Check if a Precedence header is in the email and the value of the header. The Script checks the value of the Precedence header as Project Mappings can allow Precedence: list headers and not Precedence: bulk headers.
Checking if the Catch email address (To address) matches a address which is stored within the array. If it does match one address then the email will be dropped.

/*Array for holding the email addresses in the domain mapping*/
emails = ["Address1", "Address2", "Address3"];

/*Saves Header value within a variable*/
var precedence = message.getHeader("Precedence");

/*If Header is not present it will be null, so this will check if header is in email*/
if (precedence !== null)
{
    print('Precedence Header is in email');
    
    if (precedence[0] == 'bulk' || 'Bulk') /*Checks if value of the Precedence header equals bulk*/
    {
        print('Precedence Value is bulk, now will check catch address against emails array');
        
        for (i =0; i< toAddresses.length; i++)
        {
            /*Checks all to address against emails array*/
            
            for (m =0; m< emails.length; m++)
            {
                if (toAddresses[i] == emails[m])
                {
                    /*If the catch email address matches one of the addresses within the array then it will drop the message*/
                    print('Dropping email as Recipient address = '+ emails[m]);
                    jemhUtils.dropMessage('Has Precedence:bulk');
                }
            }
        }
    }
    else
    {
        /*Output if the Precedence Value is not 'bulk'*/
        print('precedence is not bulk, will create issue and stop check');
    }
}
else
{
    /*Output if there is no Precedence header within the email*/
    print('No precedence header found');
