How to configure spamassassin

Dear All,
I have Spamassassin on my Centos 5.4. For send and receive email I use
postfix and Dovecot and Sendmail version 8.13.8. Since I have installed the
spamassassin I have not configured it. We are getting about 20 spams per
day. I want to configure it and get it working. I did google it there are
some information but all in different server, some I tried did not work. 

I will appreciate if anyone know how to configure it from scratch after
installing it.

Thanks in advance
Hatspam

clamav and spamassassin are different programs and neither one needs
another one. clamav can be integrated to spamassassin but it's not required.

both support milters. there's sa-milter that connect those MTA's to
spamassassin and clamav-milter that integrates them with clamav. 

However, I haven't seen system where both sendmail and postfix would be
running and I can't imagine any benefit of such configuration, but I can
imagine many problems in such cases.

You can also run spamc directly in a Postfix service. Slightly different
approaches are given below:

http://www.ivankristianto.com/os/ubuntu/linux-spam-filter-with-spamasassin/595/

http://www.xnote.com/howto/postfix-spamassassin.html


NOTE: both of these merely run spamc to mark up received mail. You'll
still need to separate spam from ham, either by having your users
configure their MUAs to put spam in a separate mail filter or by using a
procmail recipe to do the same thing - of course you can use a common
recipe that's used by all mail recipients.

Yes, there are hundreds of ways to integrate spamassassin and clamav.
Amavisd-new is one of the easiest to get right.

* You could run the clamd milter, which requires a fairly recent version of
postfix to support.

* You could call spamassassin at delivery time from procmail, which requires
that all of your dovecot users have actual user accounts (they might anyway)

* there are plenty of other integration glue packages, such as mailzu,
mailscanner, mimedefang

I stumbled upon amavisd-new , and it has always been flexible enough to
handle what I need, so that's what I use, but you need to go look at the
various options and pick for yourself.

Thanks a lot for replies. Do I have to install Amavisd-new and ClamAV to get
spamassassin working? Is there any other way to configure spamassassin with
postfix not installing additional software?

You should not use it if you don't know how it works and it is not 
supported anymore.
