Likely this email will, in fact, get sent to GMAIL via IPv6.

I do have good SPF and DKIM records and signing and a reasonable DMARC policy set up.

If ISC doesn’t have that yet, it might be a better alternative than turning off IPv6.

If that doesn’t solve it, I can reach out to someone at Google who can likely get the right parties involved.

I think it has been argued before that having a different email acceptance policy over IPv4 vs IPv6 is essentially a layering violation. I'm sympathetic to that argument.

More to the point: *you* could do this and there are a number of other clueful people who can make this work today. And when Google changes their rules (that you'll have to learn about once you hit the next wall), then you adjust. And you keep on doing this whack-a-mole game.

Of course there's an argument that say "mom and pop should not run their own mailserver, there are professionals for that!" but at the end of the day what this really serves is deliberate and pre-mediated centralisation, slowly but steadily stamping out small players.
