It's not our fault. With land mail, if you made a slight error in the address it would probably still get there. E-mail requires more discipline by the sender. You have to be careful. Again the legal implications are far from clear of a commercially sensitive e-mail message winding up in the wrong mailbox and being acted upon in some way by the recipient.
Lawyers are divided and believe there is no legal precedent in Australia on which to act.
Recognising at least the possibility of such an event, many larger companies include a standard legal disclosure statement on the bottom of every e-mail. But even KPMG's legal partner questions the validity of the statement. The other strange thing is that the statements are always at the end of the message. You have to read the whole message to see it.
