I had problems with a not working Email Page caused by authenticated SMTP.

My provider mijnhostingparner.nl solved this nicely by changing the script imemail.inc.php in the folder res by inserting at the top right after $ imForceSender = false;

$user = "***";
$pass = "yourpassword";
include($_SERVER['DOCUMENT_ROOT']."/mailer/mhpMail.php");

Changed at the bottem of the same script @mail in @mailTo (2x)

After this upload the folder mailer (see appendix) in the root directory.

Hope this is useful for anyone of you.

Greetings Joop
