1. To stop the sendmail process, find the sendmail process id by performing one of these actions:
• Use the ps command to get a list of processes.
# ps -eaf | grep sendmail
• Read the process id in the file /etc/sendmail.pid
# more /etc/sendmail.pid.
2. Stop the sendmail process by typing this command and the process id, for example:
# kill -9 <process_id>
3. Verify that sendmail is stopped by typing this command:
# ps -eaf | grep sendmail
4. To keep sendmail from restarting when the server is restarted, perform these steps:
• Navigate to the /etc directory and look for rc.* files.
# cd /etc # ls -lrt | grep rc.*
2. Using a text editor, open either the rc.d or rc.local file.
# vi /etc/rc.*
3. Use a number sign (#) to comment out the line that starts sendmail.
# <the-line-that-starts-Sendmail.
4. Save the file.
wq!
5. Restart the server.
# reboot
