When I try to use systemctl
to reload the sendmail
configuration I get an error. Is this a bug or should I just avoid trying to use systemctl
with sendmail
?
What is the recommended way to teach systemctl
to allow reload for the sendmail.service
?
Please no religious debates on systemd.
Output of systemctl reload sendmail
:
Failed to reload sendmail.service: Job type reload is not applicable for unit sendmail.service.
See system logs and 'systemctl status sendmail.service' for details.
And systemctl status sendmail.service
:

That error typically means that the client program (in this case
sendmail
) doesn't expose a reload method tosystemctl
to use. This is the fault of the developers/maintainers, and notsystemctl
. (Perhapssendmail
can't just plain reload the configs?)I would recommend just plain restarting
sendmail
whenever you need to reload the configuration:This will kill
sendmail
and then start it up again as a fresh daemon instance. As a result, any new config changes will take effect, but you may lose temporary data.
