/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.
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.
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
