That was Postfix 1.x (the latest release is 2.0.18). See the file
README_FILES/LOCAL_RECIPIENT_README from a Postfix source archive for
details. It starts with:

 "As of Postfix version 2.0, the Postfix SMTP server now rejects mail
  for recipients in $mydestination domains that it does not know about.
  This feature was optional with previous Postfix versions."


Greetings, Jukka
