SERVER: MailScanner: Installation (en)
Revision as of 06:34, 7 January 2025 by Onnowpurbo (talk | contribs)
Setting up MailScanner on Ubuntu may not work as expected. If you have already installed it, it is advisable to remove 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 dependencies:
sudo apt-get install mailscanner tnef unrar unzip pyzor razor
Update ClamAV database:
freshclam
Create 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 IMPORTANT! Run As Group = postfix IMPORTANT! Incoming Queue Dir = /var/spool/postfix/hold IMPORTANT! Outgoing Queue Dir = /var/spool/postfix/incoming IMPORTANT! MTA = postfix IMPORTANT! 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
Disable MailScanner's permission checks on `/var`:
vi /etc/rc2.d/S20mailscanner
Comment out:
# 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 default MailScanner settings:
vi /etc/default/mailscanner
Ensure:
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
