Better email address checking

[schumacher]

If we could include this function :

http://de.php.net/manual/en/function.getmxrr.php

then we could decrease the number of bad email addresses by checking if the host of the email address is accepting mail.

"getmxrr --  Get MX records corresponding to a given Internet host name"

How to make it work with the current pattern matching code?

function check_email($email) {
  return (preg_match('/^[-!#$%&\'*+\\.\/0-9=?A-Z^_`{|}~]+@([-0-9A-Z]+\.)+([0-9A-Z]){2,4}$/i', $email)) ? 1 : 0;
}

Thank you!
