MailScanner With Postfix on Etch

Since a few weeks I have
spammed for dead almost and i’m trying to figure out whats the best
solution is. But since I have experience with MailScanner I will
install MailScanner. In order to get MailScanner working there are a
few thing you need to do. First off install MailScanner.

apt-get install MailScanner

While it’s installing MailScanner, apt creates all the needed configuration files.

Configuring MailScanner

• Next edit the MailScanner for use with Postfix, open up
  /etc/MailScanner/MailScanner.conf with you favorite editor. You need
  adjust these options

%org-name% = yoursite
Run As User = postfix
Run As Group = postfix
Incoming Queue Dir = /var/spool/postfix/hold
Outgoing Queue Dir = /var/spool/postfix/incoming
MTA = postfix

• After you have done this you need to make sure Postfix can write to
  /var/spool/MailScanner/incoming and /var/spool/MailScanner/quarantine.
  In order to do this:

chown postfix:postfix /var/spool/MailScanner/
chown postfix:postfix /var/spool/MailScanner/incoming
chown postfix:postfix /var/spool/MailScanner/quarantine
chown postfix:postfix /var/lib/MailScanner/
chown postfix:postfix /var/run/MailScanner/
chown postfix:postfix /var/lock/subsys/MailScanner


• Final step make sure MailScanner can start, open /etc/default/mailscanner with your favorite editor and uncomment

run_mailscanner=1

• Now the base configuration of MailScanner is ready, next adjust Postfix.

Configuring Postfix

Note: Make sure you have a working version of Postfix

• Stop Postfix:

/etc/init.d/postfix stop

If Postfix is in a chrooted jail you need to adjust MailScanner accordingly. Chrooted jail is not supported here.

• Add this line to the Postfix main.cf configuration file

header_checks = regexp:/etc/postfix/header_checks

• Now put in the file /etc/postfix/header_checks

/^Received:/ HOLD

• After the configuration of Mailscanner and Postfix is complete you can move to the next part

Start MailScanner and Postfix

• Start Postfix

/etc/init.d/postfix start

• Start MailScanner

/etc/init.d/MailScanner start

• Check MailScanner

check_mailscanner

• If the output of check_mailscanner is the same as below here then you have a working version

dionysus:~# check_mailscanner
MailScanner running with pid 7589 7590
