Fixed. Feel free to also take a minute to blame Linode or whatever they're going by now for letting their network be used almost exclusively for sending spam these days.

The sender being at Linode kind of explains it. Linode's "default" shared IPv6 subnets have been blocked e.g. by Google for many years now. At some point I used to run my mail server there, and it was practically necessary to request a dedicated /64 purely so I could send mail.

We've had a dedicated /64 from them for years for this exact purpose. Without that, we simply had to disable even trying to send over IPv6.
