Rather than complicating the setup with antispam software & filtering,
I'd highly recommend implementing greylisting, it will delay emails
coming through from unknown sources but you can use a whitelist
containing known/trusted hosts to bypass the greylisting.

I highly recommend spamd (not the spamassassin daemon) which is included
with openbsd & is available from ports for freebsd (not sure about
netbsd) or postgrey if you're running postfix
