I needed to change the smart host setting for a Sendmail email server, so I edited
/etc/mail/sendmail.mc and rebuilt /etc/mail/sendmail.cf
with the m4 command.
I then attempted to restart
Sendmail, but it did not restart.# m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf # service sendmail restart Redirecting to /bin/systemctl restart sendmail.service Job for sendmail.service failed because the control process exited with error code. See "systemctl status sendmail.service" and "journalctl -xe" for details.
When I issued a systemctl status sendmail.service command
for further information, I saw the following:
# systemctl status sendmail.service ● sendmail.service - Sendmail Mail Transport Agent Loaded: loaded (/usr/lib/systemd/system/sendmail.service; enabled; vendor preset: disabled) Active: failed (Result: exit-code) since Thu 2016-08-18 15:40:49 EDT; 11s ago Process: 25578 ExecStart=/usr/sbin/sendmail -bd $SENDMAIL_OPTS $SENDMAIL_OPTARG (code=exited, status=78) Process: 25573 ExecStartPre=/etc/mail/make aliases (code=exited, status=0/SUCCESS) Process: 25570 ExecStartPre=/etc/mail/make (code=exited, status=0/SUCCESS) Main PID: 3394 (code=exited, status=0/SUCCESS) Aug 18 15:40:49 moonpoint.com systemd[1]: Starting Sendmail Mail Transport A....

When I undid the changes I had made to sendmail.mc, the issue
remained. When I used the
journalctl command to check on the problem, I saw the following:
# journalctl -xe -- -- Unit sendmail.service has failed. -- -- The result is failed.
