So how then can we stop these bounces? I can only see doing
some checking on the headers to see if the sender/reply to is
supported by the Received headers; and suppressing bounces if
it isn't. My procmail scripts do this for all the virus stuff.
Perhaps piping all unmatched local email through a catch all
account with procmail handing a more sophisticated response
behaviour is the way to hack it?
