it should be able because you are not the admin of my servers :-)

in your environemnt maybe, but it should generally have SIMPLE options
for setups where hostmaster, webmaster, postmaster is the same person

http://0pointer.de/public/systemd-man/systemd.unit.html does not contain the word "mail"
"RestartNotifyMail=root" would be what is needed in SOHO environments!

well but a) there are missing options and b) OnFailure is simply a joke
if i say "Restart=always" then OnFailure is NOT triggered
if i say "Restart=always" i want a mail if this happens
not a own unit-file


http://0pointer.de/public/systemd-man/systemd.service.html
explains "Restart" and is missing genereally on-failure + on-abort
Restart=
Configures whether the main service process shall be restarted when it exits. Takes one of no, on-success,
on-failure, on-abort or always. If set to no (the default) the service will not be restarted when it exits. If set
to on-success it will be restarted only when it exited cleanly, i.e. terminated with an exit code of 0. If set to
on-failure it will be restarted only when it exited with an exit code not equalling 0, or when terminated by a
signal. If set to on-abort it will be restarted only if it exits due to reception of an uncaught signal. If set to
always the service will be restarted regardless whether it exited cleanly or not, or got terminated abnormally by a
signal

http://0pointer.de/public/systemd-man/systemd.unit.html
exlains "OnFailure"
OnFailure=Lists one or more units that are activated when this unit enters the 'failed' state
