Guess what. I managed to get only one email, but I do not know if that is breaking something else.

In vbms_class_mail_message.php: function construct_mime_message(), in the $headermap = array I simply commented out the

//"To" => $this->to,

which I noticed was being called again in the function below

function send($testonly = false)

$result = mail($this->to, $this->subject, $this->html, $headers);
