如何使用Mandrill过滤和处理假电子邮件？

Question

With Mandrill 1.0.* and PHP 5.5 :

I have to manage a database of users (with sign up, notifications, etc), sending them emails with Mandrill.

Mandrill has a "reputation" system that handicaps you if you send too many emails to fake addresses (something like [e-mail] I guess).

So how should I handle those fake emails and "blacklist" them within Mandrill or my database ?

How do Facebook, SoundCloud, and others handle robots that spam the sign up form with fake emails ? (if those robots ever exist)

I can't find a Mandrill check DNS feature or anything similar.

mailchecker is your friend:

if(!MailChecker('[e-mail]')){
  die('O RLY !');
}

if(!MailChecker('myemail.com')){
  die('O RLY !');
}
