title: Disable PHP mailing on Mac OS?
body: <p>I'm developing a web application in PHP, and my Macbook, running Snow Leopard, is actually sending emails when PHP's mail() function is called. It's emailing customers, and that's BAD.</p>
  
  <p>I COULD prevent this in my code, but I'd rather just disable mailing for my machine. Is there a way to do this under Mac OS?</p>
