To automate the running of sendmail at startup, install the /etc/rc.d/init.d/sendmail init script sendmail.service unit included in the package. sendmail make install-sendmail The -qNm option to sendmail, where N is number of minutes, controls how often sendmail will process the mail queue. A default of 5 minutes is used in the init script. systemd unit. Individual workstation users may want to set this as low as 1 minute, large installations handling more mail may want to set it higher.
