The following breaks Postfix security:
- Changing user/group/other ownership/permissions of Postfix files
or directories
- Running non-Postfix programs with the numeric UID of the "postfix"
user (or other "security token" with the same effect).
Such usage is explicitly not supported, and that will not change.
