My understanding is that if your smail is not an open relay then you
won't have the problem of people using your mail server as a backup mail
cache without your permission.  I'm pretty sure that all recent versions
of smail come configured to prevent relaying (mine certainly was) so you
shouldn't have this problem.  Does that answer your question...?
