Hrmmm, perhaps this hasn't been thought of yet, but this is a serious idea for things like spamassassin, or the like. For this list of domains, a decent twofold effort could happen:
1) A decent push on the part of pobox.com (previously, their focus has been on protecting lots of senders, like AOL, or Earthlink), rather than commonly-forged-phishers, to get these folks on board.
2) A big old warning (possibly for these domains themselves to opt into) as a "we know we're high risk but we have an SPF record, please check it" RDNSL.
It could even be used in some cases with SpamAssassin to inject a link into the email for the location to report such forgeries. (Such info could be kept in the RDNSL, for example).
