Spamassassin
Spamassassin is an effective way to block junk mail in Postfix. Spamassassin requires Postfix to be installed before you can install Spamassassin.
Spamassassin marks junk mail with a "*****SPAM*****" notification in the e-mail topic line.

Installation
Install Spamassassin with aptitude
aptitude install spamassassin
Configuration
We create a user for the Spamassassin program.
adduser spamd --disabled-login
Open file:
/etc/default/spamassassin
We enable Spamassassin by changing the ENABLED parameter from 0 to 1
ENABLED=1
We have to configure home- and settings parameters.
SPAMD_HOME="/home/spamd/"
OPTIONS="--create-prefs --max-children 5 --username spamd --helper-home-dir ${SPAMD_HOME} -s ${SPAMD_HOME}spamd.log"
We must use a certain type of PID_FILE parameter:
PIDFILE="${SPAMD_HOME}spamd.pid"
We want Spamassassin rules and settings to update automatically:
CRON=1
The entire Spamassassin config file can be found here: https://www.dropbox.com/s/ndvpgc2jipdd4bk/etc.default.spamassassin.txt
Open the Postfix konfiguration file
nano /etc/postfix/master.conf
Find the line
smtp inet n - - - - smtpd
and below the line add:
-o content_filter=spamassassin
The end result:
smtp inet n - - - - smtpd
-o content_filter=spamassassin
Add this to the end of the file:
spamassassin unix - n n - - pipe
user=spamd argv=/usr/bin/spamc -f -e
/usr/sbin/sendmail -oi -f ${sender} ${recipient}
And in the end restart the services so the changes will apply.
service postfix restart
service spamassassin restart
Testing
Send the text found below to your e-mail server
XJS*C4JDBQADN1.NSBN3*2IDNEN*GTUBE-STANDARD-ANTI-UBE-TEST-EMAIL*C.34X
When it arrives it should have a *****SPAM***** in the topic line of the e-mail.
