Sticking to the Flatfile recipe on the Wiki, Postfix would query the Auth Backend of Dovecot. The actual user records would sit on the Dovecot side, where Postfix would only worry about valid domains etc. Fancy stuff like Aliasing would be better done on the Postfix side in this scenario although it would also be possible to have bogus User records in Dovecot to address that.
