I used procmail/sendmail to set this up.  In the procmailrc file I used
spamc with the -u option to specify a spamuser.  The database is kept
under that users directory.  This works very well.

On my system at home I use spamassassin in a filter.  But I dump mailing
list mail directly into selected folders prior to the spamassassin
filter.  Non-mailing list email is then processed by spamassassin.  This
tends to speed up the processing of incoming email since I get more
mailing list email than other things.  I have also found that most
mailing lists have little if any spam.  (besides a few flame wars but
those would be difficult to pre-filter  :).
