SpamAssasin is doing NOTHING!

No doubt it's my configuration that's at fault ...

Ubuntu Linux 10.04.2
dovecot 1.2.9
Postfix 2.7.0
SpamAssassin 3.3.1

I get hundreds of spam messages / day.  The sort that SpamAssassin was created to assassinate.

Here's my /etc/spamassassin/ file:
# Sample SpamAssassin rules. It should be localted at:
#   /etc/mail/spamassassin/
# Shipped within iRedMail project:
#   *
# See also:
#    $ man Mail::SpamAssassin::Conf

# These two lines will not affect due to Amavisd use its
# own variables setting in /etc/amavisd.conf.

So ... somewhere I must be failing to tell spam assassin something it needs to interact with dovecot correctly.  What am I missing?

Dovecot has no interaction with SpamAssassin - it is only a pop3/imap server which makes mail which has already been received available to connecting clients.  You need to configure Postfix to pipe the messages to the SpamAssassin client so that it scans them as they arrive.

This page here describes it:

It's not the simplest process - I personally find it much easier to use sendmail with procmail, where a simple .procmailrc recipe will post-process the mail after sendmail delivers it and do whatever you want with it (discard it, quarantine it, or just tag the subject line for example.)

Your spamassassin config whitelisting might be your issue.

You are also missing the Bayesian analysis features

You have to train spam assassin to statistically detect spam.

Not that using auto-learn is a two edged sword.

Procmail is a filter that can be used with any mail server not just sendmail.

Maildrop is another tool though have not looked at it for some time.

I'm reviewing those and trying to implement the instructions.
