MailScanner Installation Guide ? MailScanner

My copy of MailScanner is installed under /opt/MailScanner so all
references in the following text apply to that location. Note that
version 3 usually installed into /opt/mailscanner so you should be able
to leave the old version running on your system while you get the new
version installed and configured.

Download the distribution and unpack it into the destination directory
with a command such as

    # *cd /opt* 
    # *tar xvf MailScanner-4.01-1.tar* 
    # *ln -sf MailScanner-4.01-1 MailScanner*

    You will then need to check the paths for your particular system
    setup. Check the paths in each of these files:

    /opt/MailScanner/bin/check_mailscanner 
    /opt/MailScanner/bin/MailScanner (just line 1) 
    /opt/MailScanner/lib/MailScanner/SystemDefs.pm 
    /opt/MailScanner/etc/virus.scanners.conf 
    /opt/MailScanner/etc/MailScanner.conf 
    /opt/MailScanner/lib/*

    You should also compile the "tnef" binary for your system. The
    source code (and compiled versions for Solaris and Linux) are in the
    "bin" directory in the MailScanner tar file you downloaded. I advise
    you put the "tnef" program into somewhere such as
    /opt/MailScanner/bin/tnef. You will also need to check the
    MailScanner.conf file to ensure that the setting for "TNEF Expander"
    points to where you put the program.

    The directories

    /var/spool/mqueue
    /var/spool/mqueue.in

    *must* be in the same filesystem for MailScanner to work. If you are
    using Exim instead of sendmail, please see the Exim notes
    <exim.shtml>. Furthermore, the incoming and quarantine directories
    need to be writable by the "mail" user that Exim will be running as.

    For extra reliability, I advise putting all the directories

    /var/spool/mqueue
    /var/spool/mqueue.in
    /var/spool/MailScanner/incoming
    /var/spool/MailScanner/quarantine

    in the same filesystem. Then sendmail will ensure you don't run out
    of disk space, and handle the situation gracefully.


        Configuration Options

    These are all documented in a separate page of their own <conf.shtml>.


        Starting it & Checking it

    The check_mailscanner script mentioned above is used both to start
    it running and re-start it if it fails for some reason. It is best
    run as root by cron, a suitable crontab entry being

# 18/05/2000 JKF Ensure my e-mail virus scanner is still running
0,20,40 * * * * [ -x /opt/MailScanner/bin/check_mailscanner ] && /opt/MailScanner/bin/check_mailscanner >/dev/null 2>&1
