I have installed freebsd 11.0 using the image and disabled the sendmail on the installation utility. Still, it is getting started in the init sequence and login takes times.I have also tried disabling it in the rc.conf. However, it did not stop.send_mail_submit queue and their is one other service which is always starting up.Please give the method to disable it correctly for good.
