AVG Linux Email Server / User Manual

command (the version stands for the downloaded package version).
Switch to the unpacked directory and run the
$ ./configure –help
command if you want to get an overview of possible configuration options.
Run the
$ ./configure
command (possibly with selected options). This determines all the features
and recognizes the
AVG for Linux E-mail Server virus scanning software on
your computer.
Run the
# ./configure –install
command as root this time (again, possibly with other options you have
selected before). This updates the
qmail directory structure on your system
and also installs the
qmail-scanner-queue.pl script.
You can test the installation using the
$ ./contrib/test_installation.sh
command in the installation directory. This will send four e-mails: one normal,
two infected with the EICAR anti-virus test file, and one obvious spam to the
root's address. Ideally
Qmail-Scanner should let one through, catch the viruses, and tag the spam
as "spammy" (if
SpamAssassin is installed of course). As Qmail-Scanner
initially defaults not to notifying anyone when a virus is caught, you may have
to view the logs (e.g. syslog) to see what
Qmail-Scanner exactly did.
c)
Configuration
To enable
Qmail-Scanner to access the e-mail queue contents the qmail-
smtpd
daemon has to be told that qmail knows to use the qmail-scanner-
queue.pl
script instead of the default qmail-queue binary executable. This is
done via the TCP server control files for SMTP. See where the TCP server for
qmail-smtpd gets its rules from according to your installation options of
qmail mail transport agent. Edit the rule file and tell qmail-smtpd what IP
address range (corresponding to SMTP client IP addresses) you want
Qmail-
Scanner
to be invoked on. You should select all the addresses to be scanned.
A typical example of changing the rule file for the
qmail-smtpd daemon
follows:
#/etc/tcpserver/smtp.rules
#
