Thanks, David!  Unfortunately, Comcast does not supply the full email with
headers.  It only supplies the FROM, TO, CC, BCC, DATE and SUBJECT lines,
plus the BODY. Unless I'm missing something... adding a new header won't
help.  Please correct me if I'm wrong, or if anyone has any ideas on
getting this info into the footer.

Here's an example Comcast FBL report. As you can see, full headers are not
revealed. They even redact the name of the list, but based on the Subject
line, that has been easy to determine.

This is a Comcast Abuse Report for an email message received from domain
