The custhelp.com SPF record is beautiful, by Radu's standards.  
Unfortunately,
Blockbuster doesn't seem to have a clue about forging the custhelp.com
domain on their email.  I have repeatedly submitted problem reports,
and have configured pymilter to send frequent DSNs complaining about the
problem when they send me the forged email (instead of rejecting it), but 
they
never even respond to my problem reports.  (I suppose that would be a plug 
for
NetFlix, but Blockbuster includes 2 in-store rentals/month - although I am
getting frustrated enough to think about switching.)

So, how does one go about getting big lazy corps to fix serious email
problems?

Do they meet the requirements for being listed in trusted-forwarder.org?
