postfix from version 2.0 should return a user unknown error to the sender automatically if the recipient doesn't exist.
Maybe you have sales and info in the aliases file. If a mail (sales@foo.bar) doesn't have a local recipient, but it is still being delivered, which mailbox is it being delivered to?
