That depends on how you feed it:

- at present I'm only scanning incoming by using this chain:
  
  ISP ---pop3--->getmail | SA | sendmail ---smtp---> Postfix

- If you run SA as a Postfix service I think it scans all mail submitted
  to Postfix via SMTP on port 25

That's external. SA scores the mail so that something downstream of it
can use the score, such as procmail or a filter in the recipients MUA

If you use amavis-new as an SA front end, it can use the score to
deliver/quarantine/delete etc the message

Base rules, replaced with a new set in /var/lib/spamassassin/ the first
time you run sa_update. Your configuration and, optionally,
site-specific rules are usually in /etc/mail/spamassassin/local.cf or
you can add extra site-specific rules as /etc/mail/spamassassin/*.cf
