I’ve encountered this a few times. I’ve periodically had customers forward me these bounce messages from Google complaining about missing IPv6 rDNS when I *know* I have set it up correctly.
Typically resending an e-mail after an hour or so makes it happy.
I’d be most likely to point the finger at DNS resolution issues (quite possibly on my end, but as I’ve never been able to reproduce the issue, it’s guaranteed to go unfixed).
