[3bugs] when a user forgets his password, and replies to the email I can see all his details

I don't know if this is a real bug or not...

Bug1: when a user forgets his password and it's sent to his mail, if he replies to that mail.. the admin can see his username and PASSWORD

bug2: when a user registers, if he replies to the automatically sent email, the admin gets all his details...

Bug3: when a user recieves a PM notification mail, if he replies to that PM, the reciever can see the senders mail, and the sender can see the reciever's mail (by the way, i'm using the Prime Notify PM)
