It might help if you explained why you want to do this. What particular

As a general rule, sending a bounce is a last resort, something that you
do when you can't reject a message. That's how the system is designed to
work, and sending a bounce when you don't need to is generally
considered bad practice.

This is why: previously we used qmail, but I decided to migrate to
postfix+dovecot. On previous mail server installation (qmail) we had the
behaviour I now want to achieve - bounce mails for everyone, not only
outsiders, and thus no error message while trying to send to unknown user.
Particular problem: my boss (and his Mac Mail). :)
My boss wants this functionality. With old mail server, he could send
mail to numerous addresses, and if one of them does not exist, he would
recieve a bounce mail note for non existing user, but mails to valid
users will be sent. Now, if he misspells only one address, the mail is
not sent at all, nor even to valid addresses. That's how he sees it. No
matter what I say and try to explain which is better and why. He wants
the old functionality, as it is better for him.
So, here's one more additional question from me: why is it so
problematic if inside (my domains) users send mails to non existing mail
addresses? I assume this would not happen so often to have some impact
on server. Much much more impact have outsider mails to non existing
addresses.
