After many hours trying to figure this out, I finally found a way to enable spamassassin on a Plesk 8 box without buying the PowerPack or the SpamAssassin plugin. For the record, SpamAssassin comes installed with Plesk 8 in every configuration, it’s just not “enabled” for the mail server, Qmail.
My setup: Plesk 8.0 on Fedora Core 4.
This is based on the HOW-TO: setup a PLESK Dedicated Server tutorial.
Special thanks to the all powerful Atomic Rocket Turtle!
First, login to your server with SSH and become root.
Since Plesk moves everything around on us and breaks easily when you mess around, you need to configure yum so you can grab some Plesk pre-configured RPMS:
yum install lynx
lynx -source http://3es.atomicrocketturtle.com/installers/atomic.sh | sh
# now build your qmail-scanner-queue.pl file:
/usr/bin/qmail-scanner-reconfigure
Until I figure out how to make qmail-scanner play nice with drweb antivirus, you will need to uninstall it - who uses “DrWeb” anyway? Also, you’ll want to install qmail-scanner and clamd. qmail-scanner allows you to break into the qmail process and scan messages for spam, viruses, etc before delivery. clamd is the antivirus scanning daemon for ClamAV.
yum remove drweb-qmail drweb
yum install qmail-scanner clamd
Hit ‘y’ for yes - you want to download and install all the dependencies.
Now you should be all setup! Whew! That was easy.
Now you should send yourself the EICAR test virus to see if ClamAV is working.
Check /usr/local/psa/var/log/maillog to see if spamd is checking your mail (spamassassin):

And you can check /var/log/clamav/clamd.log to make sure ClamAV AntiVirus is working:

You can tell ClamAV to update it’s virus database twice a day like this:
freshclam -d -c 2
