电子邮件验证PHP

Question

I have the following code which (I think) will only verify the domain of the email address.

$EmailAddress = "[e-mail]";

list($User, $Domain) = explode("@", $EmailAddress);
$DomainExists = checkdnsrr($Domain, 'MX');
if($DomainExists==true){
    // Email domain exists
}
else{
    // Email domain does not exist
}

If I can, how do I verify the $User part?

Answer 1

The only guaranteed way to make sure [e-mail] exists is sending them an e-mail with a verification link.
