[Exim] locakhost headers

Currently when a local host sends an email from our network (running exim 1.33) the headers are more
or less empty with basic information

How would i go about adding the following (and changing) the following

1. add maybe the script or file that is using exim (IE: Script Name : formmail.pl
2. add maybe the scripts owner or back to #1, the path of the script
3. change the UID / GID to something other then 99 /99 (see below)

Problem: Many customers are starting to use our localhost exim as a spam relay, sending thousands of
emails an hour, and when we get a spam complaint, we have no where to look because the headers are
worthless and the exim main log doest tell you anything but if the email was sent or not
