I know this does not apply to all kinds of setup, but with virtualization and containerization it should be easy to seperate Postfix and provide a different nameserver in resolv.conf for it.
Yes, but postfix' builtin chroot isn't sufficient for this. It'll have to be some form of external jailing mechanism.
(We're using systemd-nspawn, so if *that* works, anything proper definitely will.)

There is no supported way to prevent the SYSTEM LIBRARY from picking up the resolv.conf file before changing the root directory.
