What steps can be taken to ensure the correct sendmail path is set in the PHP configuration?

To ensure the correct sendmail path is set in the PHP configuration, you can update the "sendmail_path" directive in the php.ini file to point to the correct location of the sendmail binary on your server. This ensures that PHP can properly send emails using the sendmail program.

ini_set('sendmail_path', '/usr/sbin/sendmail -t');
