title: Mandrill PHP unable to get local issuer SSL certificate
body: <p>I've installed the Mandrill PHP API on my Windows Apache server.  When trying to send an email using the code below I get the error:</p>
  
  <p>Mandrill_HttpError - API call to messages/send-template failed: SSL certificate problem: unable to get local issuer certificate</p>
  
  <p>It's not clear to me how Mandrill connects to my local issuer certificate.  My web server does have a valid certificate and can display HTTPS pages successfully.</p>
  
  <p>Any ideas?</p>
