A little PHP code I wrote, might have some places it was censored, sure you can figure it out.. simple not 100% but works at least it did a year ago when I wrote it.

<php>
error_reporting(0);
function ValidateMail($Email) {
global $HTTP_HOST;
$result = array();
if (!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $Email)) {
$result[0]=false;
$result[1]="$Email is not properly formatted";
return $result;
}
list ( $Username, $Domain ) = split ("@",$Email);
if (getmxrr($Domain, $MXHost)) {
$ConnectAddress = $MXHost[0];
} else {
$ConnectAddress = $Domain;
}
$Connect = fsockopen ( $ConnectAddress, 25 );
if ($Connect) {
if (ereg("^220", $Out = fgets($Connect, 1024))) {
fputs ($Connect, "HELO $HTTP_HOST\r\n");
$Out = fgets ( $Connect, 1024 );
fputs ($Connect, "MAIL FROM: <{$Email}>\r\n");
$From = fgets ( $Connect, 1024 );
fputs ($Connect, "RCPT TO: <{$Email}>\r\n");
$To = fgets ($Connect, 1024);
fputs ($Connect, "QUIT\r\n");
fclose($Connect);
if (!ereg ( "^250", $To )) {
$result[0]=false;
$result[1]="Server rejected address";
return $result;
}
} else {
$result[0] = false;
$result[1] = "No response from server";
return $result;
}
} else {
$result[0]=false;
$result[1]="Can not connect E-Mail server.";
return $result;
}
$result[0]=true;
$result[1]="$Email appears to be valid.";
return $result;
} // end of function
$Email = addslashes($_GET['email']);
$email_status = ValidateMail($Email);
//echo $email_status[1];
print_r($email_status);
</php>
