The official postfix.org online documentation is updated
frequently and is correct for the current version of postfix.
  The online docs also usually indicate which version of
postfix it applies to when behavior changes.

If there's a contradiction, always go with the official docs
bundled with your version of postfix, which are correct for
your version of postfix.
