  2. Update the package list: sudo apt-get update
  3. Remove the Sendmail package: sudo apt-get purge sendmail
  4. Remove the configuration files: sudo apt-get purge sendmail-config
  5. Remove the mail queue: sudo rm -rf /var/spool/mqueue

  3. Remove the Sendmail package: sudo dpkg --remove sendmail
  4. Remove the configuration files: sudo dpkg --remove sendmail-config

After removing Sendmail, you can verify that it's no longer running by checking the service status:

sudo systemctl status sendmail

This should output "sendmail.service - Sendmail Send and Receive Mail" with a status of "loaded" or "disabled".

Note: If you're using a DigitalOcean droplet, you may want to consider removing the Sendmail service to prevent potential security vulnerabilities. However, if you're using Sendmail for a specific purpose, such as sending emails from a script, you may need to configure an alternative email service or use a different method to send emails.
