I don't bother checking outgoing mail. Checking inbound mail stops your
machines getting infected by the latest worm in the first place, so you are
unlikely to send out any nasties anyway. But it seems a lot of people do

You don't have to stick to the supplied header names, feel free to
personalise them a bit. Of course I prefer people to leave MailScanner in
the header somewhere, as it gets me more hits (and hence publicity, and
