I am more worried about spam filters of they are case sensitive, I had to train my mail programs (gmail [please don't shout at me...] and thunderbird), because some of the pd mails went to spam. maybe you can send out a testmail with the new header and see if it comes through.
I hope, you don't have "Pd" and "pd" as well as "PD" and maybe "pD" in your blacklist. ;)
