My guess is that postfix runs as postfix. At least processes like local, smtpd, bounce etc run as that user. But beyond that I have no idea how to find that out. At least there's nothing in the postfix.service or postfix@.service about that. So I've changed the files to dovecot:postfix 664, but same error.
