[SAtalk] filtering spam tagged email before hitting exchange 2000

[gentian]

Hi list,   I am very new to spamassassin and i want to setup a gateway for external spam and then i want to relay mail from spamassassin to Exchange 2000. I read that spamassassin just tags the mail, doesn'filter it and i should filter it on Exhange 2000 and that was done by some other tools. The problems is that i do not want to mess around with Exchange 2000 and install other stuff in there. It has already enough load and problems so I was wondering if there is any way to filter tagged email before it hits Exchange 2000, something that filters it at at tehe same machine where spamassassin lives.    Any idea is apprecciated.     Thanx in advance   Gentian
