Postfix strange behavior

[dedisoft]

Hi,

I've a strange behavior with Plesk 12 on Ubuntu 12.

Each person who successfully send a mail receives a successfully notification.

How can I disable it without modify Postfix configuration manually ?

Is there any option on Plesk that I haven't seen, or any other possible error ?

Thanks in advance

What kind of notification do you mean? Can you show it here?
