title: How can I send emails via PHP on a VPS with no smtp / mail server?
body: <p>I'm moving a few sites from a full managed cPanel VPS to a cheaper VPS that basically has nothing (runs ubuntu 12.04).</p>
  
  <p>The PHP scripts that I have send email via the <code>mail()</code> function.</p>
  
  <p>I'd rather avoid installing any mail server stuff onto the VPS. I'm open to paid mail services or other methods. I'm not even sure what this would be called so finding it hard to find solutions.</p>
