Title: Update KEmail.php

Using
$command>bindParam(':additional_headers',json_encode($additional_headers),PDO::PARAM_STR);
gives an error: "Fatal error: Only variables can be passed by reference" in E_STRICT error handling mode. So the argument json_encode($additional_headers) can be replaced with a variable.
