One of the standard configurations is as a "null client".
http://www.postfix.org/STANDARD_CONFIGURATION_README.html#null_client
A null client is a machine that can only send mail. It receives
no mail from the network, and it does not deliver any mail
locally. A null client typically uses POP, IMAP or NFS for mailbox
access.
If that is what you want then setting up the configuration as
described there is the way to do it.
If you only want to prevent some local addresses from receiving mail
while allowing the rest then a possible way is to add a check to
smtpd_recipient_restriction:
smtpd_recipient_restrictions =
...
check_recipient_access hash:/etc/postfix/recipient-access,
...
And in that file list addresses to be rejected. Use postmap to update
the associated lookup table.
m...@example.com REJECT User unknown in local recipient table
s...@example.com REJECT User unknown in local recipient table
al...@example.com REJECT User unknown in local recipient table
b...@example.com REJECT User unknown in local recipient table

And I am sure there are other alternatives too.
