PocedureTo Disable the sendmail Daemon

 

1. Change to the /etc/init.d directory.

   cd /etc/init.d

2. Stop the sendmail daemon if it is running.

   ./sendmail stop

3. Modify /etc/default/sendmail by adding MODE="".

   If the sendmail file does not exist, create the file and then add MODE="".

   If a user accidentally runs sendmail start, or if a patch restarts sendmail, then adding this modification prevents sendmail from starting up in daemon mode.
