SpamAssassin

Update the SpamAssassin matching patterns and compile them:

# sudo -u spamd sa-update && sudo -u spamd sa-compile

You will want to run this periodically, the best way to do so is by setting up a Systemd/Timers.

Create the following service, which will run these commands:

/etc/systemd/system/spamassassin-update.service

[Unit]
Description=spamassassin housekeeping stuff
After=network.target

[Service]
User=spamd
Group=spamd
Type=oneshot

ExecStart=/usr/bin/vendor_perl/sa-update
SuccessExitStatus=1
ExecStart=/usr/bin/vendor_perl/sa-compile
ExecStart=!/usr/bin/systemctl -q --no-block try-restart spamassassin.service

# uncomment the following ExecStart line to train SA's bayes filter
# and specify the path to the mailbox that contains spam email(s)
#ExecStart=/usr/bin/vendor_perl/sa-learn --spam <path_to_your_spam_mailbox>

Then create the timer, which will execute the previous service daily:

/etc/systemd/system/spamassassin-update.timer

[Unit]
Description=spamassassin house keeping

[Timer]
OnCalendar=daily
Persistent=true

[Install]
WantedBy=timers.target

Now you can start and enable spamassassin-update.timer.

Install and setup clamd as described in ClamAV.

Follow one of the above instructions to call SpamAssassin from within your mail system.

Install the package. Then install the ClamAV perl library as follows:

# /usr/bin/vendor_perl/cpanp -i File::Scan::ClamAV

Add the 2 files from https://wiki.apache.org/spamassassin/ClamAVPlugin into . Edit and update to point to your Clamd socket location (default is ).

Finally, restart spamassassin.service.

Vipul's Razor is a distributed, collaborative, spam detection and filtering network.

Make sure you have installed SpamAssassin first, then:

Install the package.

Register with Razor.

# mkdir /etc/mail/spamassassin/razor
# chown spamd:spamd /etc/mail/spamassassin/razor
# sudo -u spamd -s
$ cd /etc/mail/spamassassin/razor
$ razor-admin -home=/etc/mail/spamassassin/razor -register
$ razor-admin -home=/etc/mail/spamassassin/razor -create
$ razor-admin -home=/etc/mail/spamassassin/razor -discover

To tell SpamAssassin about Razor, add the following line to /etc/mail/spamassassin/local.cf:

razor_config /etc/mail/spamassassin/razor/razor-agent.conf

To tell Razor about itself, add the following line to :

razorhome = /etc/mail/spamassassin/razor/

Finally, restart spamassassin.service.
