When running under systemd, what’s done with text the program prints to
stdout/stderr depends on the `StandardOutput` and `StandardError`
directives in the unit file. Those are unset in this unit file (which is
probably appropriate), which means they inherit defaults from a global
config file. If unset in that config file, in turn, the default is to
write the messages to the system journal. When that is done, the journal
entries are automatically given syslog-style metadata, i.e. an
identifier, facility code, and priority level. If unspecified, the
facility code is set to “daemon”; however, since nullmailer is in the
business of handling e-mail, “mail” is a better choice out of the
available set.
