Thanks for your reply.
I'm now very confused. Looking at
https://github.com/dovecot/docker/blob/main/2.3.21/Dockerfile this

I would be fantastic if dovecot could release arm64 debian packages to

- fix other downstream docker images like docker mailserver and mailcow
It looks like arm64 is gaining a lot
