I would like to have MailScanner on a Ubuntu Dapper server for internal server. There are many receipts including a good one at wiki. Anyway, I add a few modification to make it more easier to debug. Follow me.

1. Install Postfix

   sudo apt-get install postfix
   

2. Add below line to /etc/postfix/main.cf

   header_checks = regexp:/etc/postfix/header_checks
   

3. Create file /etc/postfix/header_checks

   /^Received:/ HOLD
   

4. Generate its map

   sudo /etc/postfix/header_checks
   

5. Install MailScanner and companions

   sudo apt-get install mailscanner tnef unrar unzip pyzor razor dcc-client
   

6. Change /etc/MailScanner/MailScanner.conf as you need

   %org-name% = your-site
   %org-long-name% = your-long-site
   %web-site% = www.your-site.com
   
   Run As User = postfix
   Run As Group = postfix
   
   Incoming Queue Dir = /var/spool/postfix/hold
   Outcoming Queue Dir = /var/spool/postfix/incoming
   MTA = postfix
   
   Spam Actions = deliver header "X-Spam-Status: Yes"
   High Scoring Spam Actions = delete
   
   Syslog Facility = local0
   Log Spam = yes
   SpamAssassin User State Dir = /var/spool/MailScanner/spamassassin
   

7. Change /etc/MailScanner/spam.assassin.prefs.conf

   bayes_path /var/spool/MailScanner/spamassassin
   razor_config /var/lib/MailScanner
   

8. Edit /etc/default/mailscanner

   run_mailscanner=1
   

9. Create directory and change permission

   sudo mkdir /var/spool/MailScanner/spamassassin
   sudo chown -R postfix:postfix /var/spool/MailScanner
   sudo chown -R postfix:postfix /var/lib/MailScanner
   sudo chown -R postfix:postfix /var/run/MailScanner
   sudo chown -R postfix:postfix /var/lock/subsys/MailScanner
   

10. Edit /etc/syslog.conf

    local0.* -/var/log/mailscanner.log
    

11. Restart mailscanner

    sudo /etc/init.d/syslogd restart
    sudo /etc/init.d/mailscanner restart
    sudo /etc/init.d/postfix restart
    

All done. If you have questions about postfix, please read the wiki for more details.
