Is there a way to detect fake domain name of email address? Using Perl, php, javascript?

If anyone knows how can we detect fake domain names of email addresses, it would be a great help.

Note, that I don't want to validate an email. I want to know if the email domain name exists or not.

in php there is a function checkdnsrr

How do you check if a domain name exists?

if (checkdnsrr('test.nl', 'A')) // or use ANY or for other see above link
{
    echo 'Domain exists';
}
else 
{ 
    echo 'Domain does not exist'; 
}

------------------ Code that is working -------

 <?php 

if (checkdnsrr('google.com', 'A')) // or use ANY or for other see above link
{
    echo 'Domain exists';
}
else 
{ 
    echo 'Domain does not exist'; 
}

?>
//Output = Domain exists

// 

if (checkdnsrr('fakewebtesting.com', 'A')) // or use ANY or for other see above link
{
    echo 'Domain exists';
}
else 
{ 
    echo 'Domain does not exist'; 
}

?>
  //Output = Domain does not exists

I hope you are extracting domain name from email and using it in this function.
