Jump to navigation Jump to search

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

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!

Spam Actions = deliver header "X-Spam-Status: Yes"
High Scoring Spam Actions = delete

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

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

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
