Usage

  1. Install to /etc/systemd/system:

    • send-mail@.service: systemd unit
    • send-mail: Script invoked by send-mail@.service to send an e-mail

  2. Optionally configure recipient's and sender's e-mail addresses in send-mail:

    RECIPIENT=jdoe@example.com
SENDER=jschmoe@example.com

    These default to root@<hostname> and <failed-unit-user>@<hostname>.

  3. Add to the unit(s) of whose failures you would like to be notified:

    [Unit]
...
OnFailure=send-mail@%N.service
...

  4. Reload the modified unit(s):

    $ sudo systemctl daemon-reload
