This doesn't work.  I have a nightly cron job (run as root) I'm trying
to debug so I have it output debug information always.  I also have an
alias for root mail to me (local user) in /etc/aliases.  With sendmail,
this information was mailed to me.  Logs tell me last 3 days the job
ran, however I did not receive any of the mails.

I tested interactively by trying to send mail to root using the mail
program; it fails like this:

  # mail root
  Subject: Testing system mail 2
  Hi,
  
  Can you see me?
  
  Cheers,
  EOT
  /usr/sbin/sendmail: No such file or directory
  "/root/dead.letter" 13/241
  . . . message not sent.

After I install sendmail again and start the daemon with systemctl, the
above command succeeds and I (regular local user) get the test mail.
