That tarball is still there but I should update it with my more recent code.

I have code to check DKIM, SPF, DMARC, and ARC, add an Authentication-Results: 
header, and optionally put the results in a MySQL database.  DKIM, SPF, and 
DMARC use the usual libraries.  There's no C library for ARC that I would trust 
so the ARC checker calls out to a python daemon on messages that have ARC 
headers.

just enables blowback bounce spam.
