Setting up MailScanner on Ubuntu seems not to work.
If you have already installed it, it is advisable to delete it first:

/etc/init.d/mailscanner stop
apt-get remove mailscanner

==Postfix Installation==

Install postfix:

sudo apt-get install postfix

Add to the end of /etc/postfix/main.cf:

vi /etc/postfix/main.cf

header_checks = regexp:/etc/postfix/header_checks

Create the file /etc/postfix/header_checks:

vi /etc/postfix/header_checks

/^Received:/ HOLD

==MailScanner Installation==

Install MailScanner and its companions:

sudo apt-get install mailscanner tnef unrar unzip pyzor razor

Update the ClamAV database:

freshclam

Make directories for SpamAssassin and set permissions:

mkdir /var/spool/MailScanner/incoming
mkdir /var/spool/MailScanner/spamassassin
chown -Rf postfix /var/spool/MailScanner

Backup and edit MailScanner.conf:

cp /etc/MailScanner/MailScanner.conf /etc/MailScanner/MailScanner.conf.bak
vi /etc/MailScanner/MailScanner.conf

Set the following in MailScanner.conf:

%org-name% = ORGNAME
%org-long-name% = ORGFULLNAME
%web-site% = ORGWEBSITE
Run As User = postfix '''ATTENTION!'''
Run As Group = postfix '''ATTENTION!'''
Incoming Queue Dir = /var/spool/postfix/hold '''ATTENTION!'''
Outgoing Queue Dir = /var/spool/postfix/incoming '''ATTENTION!'''
MTA = postfix '''ATTENTION!'''
Virus Scanners = clamav
Spam List = SBL+XBL
SpamAssassin User State Dir = /var/spool/MailScanner/spamassassin

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

Disable permission check by MailScanner on /var:

vi /etc/rc2.d/S20mailscanner

Edit to:

# check_dir /var/spool/MailScanner ${user:-mail} ${group:-mail}
# check_dir /var/lib/MailScanner ${user:-mail} ${group:-mail}
# check_dir /var/run/MailScanner ${user:-mail} ${group:-mail}
# check_dir /var/lock/subsys/MailScanner ${user:-mail} ${group:-mail}

Set the default MailScanner:

vi /etc/default/mailscanner

Make sure:

run_mailscanner=1

Create Directories & Change Permissions:

sudo cp /etc/MailScanner/MailScanner.conf /etc/MailScanner/conf.d/
sudo mkdir /var/spool/MailScanner/spamassassin
sudo mkdir /var/run/MailScanner
sudo mkdir /var/lock
sudo mkdir /var/lock/subsys
sudo mkdir /var/lock/subsys/MailScanner
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

Edit /etc/syslog.conf:

vi /etc/syslog.conf

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

Start the system:

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

==Fix for Ubuntu 8.04==

If MailScanner deletes its directories, add the following to /etc/rc.local:

mkdir /var/run/MailScanner
mkdir /var/lock/subsys
mkdir /var/lock/subsys/MailScanner
chown -R postfix:postfix /var/run/MailScanner
chown -R postfix:postfix /var/lock/subsys/MailScanner
/etc/init.d/postfix restart
/etc/init.d/mailscanner restart
