It is important that you use the recipient map! See my comment below.

http://www.postfix.org/LOCAL_RECIPIENT_README.html

What the map does is map valid recipient addresses to local mailboxes.
All non existing recipient addresses will be rejected then with a valid
DSN.

Sure :| If you review one of my previous answers in the thread about
Cyrus-IMAPd you will find a warning about using the create on post
option of the autocreate patch. You now see the effect: each spam mail
to a local domain but with a random, non existing account will create
you a new mailbox.
