Deploying Amavisd-logwatch

By eric

I was looking for way to make my SPAM filtering more effective and came across this great tool from Mike Cappella called amavisd-logwatch.

On his web site, it says he doesn’t like waiting for package maintainers, so its just a tarball. Since my installs are Debian based, I created a deb for it. My .deb creating skills are not perfect, but it works. The deb was built on sid and is available here.

Download the Debian package and install it:

mail:~# dpkg -i amavis-logwatch_1.49.09-1.1_i386.deb
Selecting previously deselected package amavis-logwatch.
(Reading database ... 37342 files and directories currently installed.)
Unpacking amavis-logwatch (from amavis-logwatch_1.49.09-1.1_i386.deb) ...
Setting up amavis-logwatch (1.49.09-1.1) ...
Processing triggers for man-db ...

Leaving the defaults are safe in the config file. The one thing that does need to be changed is the additional cron script that I added to the installer. It will email the output of the script when cron.daily runs. If you do not want this to happen, then just delete the file /etc/cron.daily/amavis-logwatch. To have the script run, you have to edit it and change the defaults to reasonable defaults (like proper From, To, and CC email addresses). Also make sure to change the /var/log/mail.log file if that isn’t the location of your mail log.

$SUMMARY=`/usr/bin/amavis-logwatch --detail 5 -f /etc/amavis-logwatch.conf /var/log/mail.log`;
...
# Set the email header fun
$FROM = ""Postmaster" <postmaster \@example.com>";
$TO = ""To" <to \@example.com>";
$CC = ""CC" <cc \@example.com>";
</cc></to></postmaster>

Once you have made those changes, you will receive a nightly report with your amavisd-new log information.
