I am not familiar with the spamassassin ports:
Code:
> cd /usr/ports && make search display=path key=spamassassin
...
Path: /usr/ports/mail/spamass-milter
Path: /usr/ports/mail/spamass-rules
Path: /usr/ports/mail/spamass-rules_du_jour
...
Perhaps check the pkg-descr in each of those ports for more info. (Or check freshports.org.)
