thanks again Stephen!
I've try to find how to disable the plug in but it seems there is nothing in the Admin panel.
In the php code the function is also in the PHPmailer, so, I do apologise, but I have not a strong PHP background (actually is the first time I cope with it) and I don't have a clue where to comment the code to receive the confirmation message.
May I ask you directions?
Thanks, and thanks again.
