Not so. 

Spamkiller was designed from the outset to sit behind Spamassassin. Its
purpose is to quarantine spam and to pass ham to a local Postfix
instance for delivery to local machines on my LAN. Bounces and other
rejections are NEVER sent outside my LAN.

The local Postfix does four things:
- BCCs all incoming and outgoing mail to a searchable local mail archive
- uses a local Dovecot MDA to distribute mail to other systems on my
  LAN 
- collects logwatch reports and other system messages from other hosts
  on my LAN and forwards them to my usual (non-root) user.
- Accepts outbound messages from hosts on my LAN and forwards them via
  my ISP to external recipients.

I use a PHP page to inspect quarantined spam.
