How to disable "sender non-delivery notification" in postfix?

I want postfix to stop sending non-delivery notifications to my local account, here is example from my log

17:47:08  A727B62C6F61: message-id=<20121124174708.A727B62C6F61@mail.***********>
17:47:08  F151362C6F5F: sender non-delivery notification: A727B62C6F61
17:47:08  A727B62C6F61: from=<>, size=4676, nrcpt=1 (queue active)
17:47:08  F151362C6F5F: removed
17:47:08  warning: dict_nis_init: NIS domain name not set - NIS lookups disabled
17:47:08  A727B62C6F61: to=<**********>, relay=local, delay=0.01, delays=0/0.01/0/0, ...

How can I configure this in my main.cf?

Solution 1:

The answer:

master.cf

bounce    unix  -       -       n       -       0       bounce

should be changed to:

master.cf

bounce    unix  -       -       n       -       0       discard

Solution 2:

To control where bounce notifications are sent, and when, look at the following settings:

bounce_notice_recipient
notify_classes

Both are described here: http://www.postfix.org/bounce.8.html
