depending on your MTA (postfix, sendmail, ...) or your MDA (maildrop, 
procmail, ...), there are various ways to integrate spamassassin:

- a proxy. an example is amavisd-new (it calls SA internally, so you 
don't need to run spamd)
- a milter, if your MTA supports milters (sendmail and postfix do) and 
you are confortable with this.
- a program or script calls "spamc" and you have spamd running
- a program calls spamassassin (not recommended, except for testing and 
debugging)
- other
