$mail_body="Dear sir,

if (mail ($to,$subject,$mail_body,$from))
echo 'mail delivered successfully';
echo 'problem delivering mail';
Have you set up postfix or some other MTA on the droplet?

Try installing sendmail. If you are on Ubuntu 'sudo apt-get install sendmail'

PHPMailer with a gmail account is more likely to work consistently though.
Or actually on centos yum install sendmail
