That is not what Jorge asked, I'm sure he is aware of what he can do at 
the MTA level.

Jorge -

you can use the Non Spam Actions within Mailscanner.conf

Set it to a rule such as:

Non Spam Actions = %rules-dir%/nonspam.rules   

inside of nonspam.rules make an entry for the default and the naughty 

FromOrTo:   naughty at   delete
FromOrTo:    Default    deliver header "X-Spam-Status: No"

That's it.
