Maybe, The person who runs fep06.mfe.bur.connect.com.au would know more, since it is that server which rejected the mail. My guess is that he does not allow yahoo envelopes from non-yahoo servers. He may be more strict in his match and not allow 'example.com' envelopes from servers whose dns does not include 'example.com'. Postfix just reports what the other mail server had in its reply: whoever set that reply string would have more information on what it means.
