We have however seen some posts in debian-user where people are confused about why their service set up on a new release can no longer send email, e.g. a monitoring service. When we have dug into it, it's been because the service gained a systemd service unit with directives that prevent writing to the postfix spool. So there is some thought needed if adding protections to a service unit that sends email, if it is to be run on a system with a setup like Postfix.
