MailScanner is highly configurable using a very easy-to-use system of rulesets. Virtually every configuration option can, for example, be controlled on a per-user, per-domain or per-IP basis.

It's assumed that you have already installed and configured Postfix according to this tutorial:
Installing Postfix with MySql backend and SASL for SMTP authentication

1. Add backports to your apt sources (pico /etc/apt/sources.list)

deb http://www.backports.org/debian lenny-backports main contrib non-free

2. Add the backports keyring and update apt

apt-get update
apt-get install debian-backports-keyring
apt-get update

3. Install required packages (ClamAV, SpamAssassin, Razor and required libs for MailScanner)

apt-get install clamav clamav-base clamav-freshclam libclamav6 spamassassin razor unzip libarchive-zip-perl libconvert-tnef-perl libhtml-parser-perl libmime-tools-perl libmime-perl libcompress-zlib-perl libconvert-binhex-perl libdbd-sqlite3-perl libfilesys-df-perl libsys-syslog-perl libsys-hostname-long-perl libmailtools-perl libole-storage-lite-perl libnet-cidr-perl

4. Install libnet-dns-perl from backports

apt-get -t lenny-backports install libnet-dns-perl

5. Install MailScanner

apt-get install mailscanner

6. Enable MailScanner (pico /etc/default/mailscanner)

run_mailscanner=1

7. Edit MailScanner configuration (pico /etc/MailScanner/MailScanner.conf)

Run As User = postfix
Run As Group = postfix
Incoming Queue Dir = /var/spool/postfix/hold
Outgoing Queue Dir = /var/spool/postfix/incoming
MTA = postfix
Always Include SpamAssassin Report = yes
Send Notices = no
Spam List = RFC-IGNORANT-DSN SORBS-SMTP spamhaus-ZEN spamcop.net CBL
Spam Lists To Reach High Score = 2
High SpamAssassin Score = 8
Rebuild Bayes Every = 86400
Wait During Bayes Rebuild = yes
High Scoring Spam Actions = delete

8. Create razorhome, discover razor servers and register for identify

razor-admin -create
razor-admin -register

9. Make Postfix put all messages on hold to allow MailScanner to scan the messages (pico /etc/postfix/main.cf)

header_checks = regexp:/etc/postfix/header_checks

10. Create the header checks file referenced by previous line (pico /etc/postfix/header_checks)

/^Received:/ HOLD

11. Restart MailScanner and Postfix

/etc/init.d/mailscanner restart
postfix reload
