is rumored to have said:

how do you currently run postfix in containers?

I don't (and neither do most Postfix users) because a robust MTA installation is a terrible fit for a Docker container, as it will include a lot of non-Postfix tools and daemon processes and needs to maintain its own internal and external state (e.g. queue state and mailboxes) across restarts and crashes.

What problem do you think a Postfix container would solve? If you say "configuration complexity" then you're using containers for a bad reason that you will regret. There's no single correct configuration that will work everywhere.

I do run a couple of very simple Postfix instances inside FreeBSD jails (for aggregating relay for customer through one trustworthy node) but they are quite different from Docker containers and are almost indistinguishable internally from an installation on bare metal.
