There's still a lot of ancient mail servers out there in v4 land, that were set up before PTRs were pseudo-required by most places, so we end up cutting them some slack under a grandfather clause. There's probably less than a dozen ASNs that have mailservers that speak IPv6 that were deployed before requring PTRs became common, so they have much less of an excuse not to do so....
