I do it for our company and top-managers says "drop every emails with spam level 7 or higher"you shouldnt discard mail, only cause flagged by spamassassin this is not allowed i.e in germany by law, if you do this for customersuse hold ( for manual inspection ) or tell spamass-milter to reject them at smtp income level additionally you may load sanesecurity spam sig to clamd, clamav-milter and reject or hold them at smtp income level
I am small man, I do what managers says :-( J.
