Description
The GeoIP plugin for qpsmtpd lets you know where your mail server is receiving mail from. If you're receiving too much spam from a particular location, this will help track it down. You can then use that info to reject connections from that place taking the load off your server.
Because the databases have been updated new perl modules are required to support GeoIP v2. The core modules have a large number of dependencies and we have decided that it is not practical for the Koozali team to maintain them all.
As a result you will now need the OpenFusion repo to install smeserver-geoip We will be syncing their mirror in due course to speed up installs and updates.
yum --enablerepo=smeaddons install smeserver-extrarepositories-openfusion signal-event yum-modify config set UnsavedChanges no
You can now follow the instructions below to install GeoIP.
Note that smeserver-wbl and spamassassin are also being updated to work with GeoIP v2
If you do not want to update you will need to follow something like this:
db yum_repositories setprop smecontribs Exclude smeserver-geoip signal-even yum-modify
Installation
yum install smeserver-geoip --enablerepo=smecontribs,openfusion
then
signal-event geoip-update
or if you prefer to reboot your server
signal-event post-upgrade; signal-event reboot
Updating the geoip database is performed by issuing the following command:
signal-event geoip-update
This contrib adds a template to /etc/crontab to automatically update the database once a month. It's set to do so at midnight on the 5th of each month. If you have a paid subscription through the maintainer of this database (http://dev.maxmind.com/geoip/geoipupdate/) you can update more often. If you do want to update more often, you will have to create a custom template to handle the change. In addition, you will be supplied login credentials that have to be inserted into the file /etc/GeoIP.conf for the update to complete. The file is not templated so it will survive reboots. Use your favorite text editor to insert the information into this file.
Testing
Now that the package and database are installed, we can test it (refer to Country Code list at end of page as required).
geoiplookup 216.17.211.37
It should return:
GeoIP Country Edition: US, United States
It gives us the country code (US) and the long name (United States). Let's test it again with a domain name.
geoiplookup contribs.org
Same result. So we know it works with ip addresses or domain names. Let's test it again around the world.
geoiplookup gormand.com.au
It should return:
GeoIP Country Edition: AU, Australia
One last time:
geoiplookup swerts-knudsen.dk
It should return:
GeoIP Country Edition: DK, Denmark
Usage
Tracking e-mail
The qpsmtpd GeoIP plugin should now do its work. Check the qpsmtpd logs and you'll see the countries from where mail is sent.
cat /var/log/qpsmtpd/current
We'll use a simple shell script to do the work then we'll run it.
First, create the the script.
vi geoipstats.sh
Insert the following: Code:
#!/bin/sh # Read the qpsmtpd log file. # Read all of the countries and count them. cat /var/log/qpsmtpd/* | \ grep 'GeoIP Country:' | \ sed -e 's/^.*\(..\)$/\1/' | \ sort | uniq -c | sort -n
Now run the script. It will show the number of messages sent by country code.
sh geoipstats.sh
See where your mail is coming from. Now ask the question, "why am I receiving thousands of email from RU -Russia? I don't even know anyone there." Good point. In addition, your server has to process all that mail, taking resources away from the server. In the next section we'll block the countries that we consider bad.
Blocking email
Add the values to the SME CADNHO db. In our case, Russia and Poland seem to causing issues. You can type in any country codes you wish.
config setprop qpsmtpd BadCountries RU,PL
Signal the email-update event.
signal-event email-update
No more mail from domains ending on .ru or .pl. The beauty of this is that the SME Server lookups happen locally on the local database rather than looking up the IP address via dns. This results in very fast responses. In addition, the plugin happens before most other plugins. This means the mail is dropped before the SME Server even has to check to see if it's on a blacklist or if it's spam.

Troubleshooting
At April 2012 there may be some problems with countries not being blocked, possibly related to the way the geo database is updated for free users. User experience and opinion vary, and following a complaint, the original forum post about this has been deleted - http://forums.contribs.org/index.php/topic,48560.0.html
Users are advised to determine the effectiveness of the database for themselves.
