You don't mention your OS or distribution, so it's hard to provide
specifics.  The way I run it on RedHat/Fedora/CentOS is to run spamd
and call spamc from each user's .procmailrc like this:

======== 8< -------------
PATH=/bin:/usr/bin:/usr/local/bin
MAILDIR=$HOME/Mail
# LOGFILE=$MAILDIR/from
LOGFILE=/dev/null

# Put any rules to bypass SA here, e.g.
:0:
* ^List-Id: <users\.spamassassin\.apache\.org>
/var/spool/mail/$LOGNAME

:0fw
| spamc

# Any spam with 9 or more * will be summarily punted.
:0 H
* ^X-Spam-Level: \*\*\*\*\*\*\*\*\*
/dev/null

# Uncomment this to divert remaining spam to a spam bucket.
# Else it goes to your mailbox.
# :0:
# * ^X-Spam-Status: Yes
# $HOME/Mail/caughtspam
======== 8< -------------

Not sure I understand, but I think the answer is spamc, which feeds it
to spamd.  Then spamd filters it and returns it with the desired spam
markup.

After it comes back from spamc, what happens depends on the following
procmail "recipes".  You can divert it, delete it (to /dev/null), or
send it on to the recipient.
