Rolf,
Since most mailservers have disabled VRFY long ago due to spammers and other
miscreants.
Easiest way is to use class.smtp.php form phpmailer using the following:
$smtp = new SMTP
if (empty($smtp->Connect())) return false; // Connect failure
if (empty($smtp->Hello("yourmailerver.com")) return false; //Maybe not a
mailserve
if(empty($smtp->Recipient($to))) return false; //No such user
$smtp->Close(); // Found user so abort transaction.
return true;
