In Smart Hospital we have used phpmailer https://github.com/PHPMailer/PHPMailer library which is used by many popular php application like WordPress, Drupal, SugarCRM, Yii, Joomla etc.
By default SendMail is set as Email Engine in Setup > Settings > Email Setting. SendMail can only work and send emails if you cpanel hosting supports it. If SendMail not sending email then contact to your hosting provider. Since SendMail is easiest but less reliable so check email recipient account Spam folder because sometimes SendMail sent emails detected as spams (if using SendMail). Another and best option is to use SMTP as email engine. You can use Gmail or any other free SMTP service provider to use SMTP email engine.
If you are using your hosting smtp or any other provider smtp service then check their documentation for smtp settings.
