Send from field on notification setting page doesnt work

I am having this same issue... the notification from page is not being used in the email sent out.

I use the following script to set up my smtp server. The result is that the send from field is always same with the smtp login user name. I guess gravityforms doesn't set the send from field.

add_action('phpmailer_init','smtp_phpmailer_init');
function smtp_phpmailer_init($phpmailer) {

    $smtp_options = get_option('smtp_options');

    // Set Mailer value
    $phpmailer->Mailer = 'smtp';

    // Set SMTPSecure value
    $phpmailer->SMTPSecure = $smtp_options['smtp_secure'];

    // Set Host value
    $phpmailer->Host = $smtp_options['host'];

    // Set Port value
    $phpmailer->Port = $smtp_options['port'];

    // If usrname option is not blank we have to use authentication
    if ($smtp_options['username'] != '') {
        $phpmailer->SMTPAuth = true;
        $phpmailer->Username = $smtp_options['username'];
        $phpmailer->Password = decrypt_string( $smtp_options['password'], CRYPT_KEY );
    }
}
