This was an example. Ok... they use a relay open mailserver that is on no

But this is exactly the point.
Valid (e.g.!!!) hotmail.com eMails should come from an outgoing
hotmail.com smtp server. If they don't they're most probably faked

There is not any switch of tcpserver that helps detect this and there is
no rule that you can specify in a cdb file that prevents this spam, yet.
