SpamAssassin is a mail filter to identify spam.

## Installation

Install the spamassassin package.

This article or section needs language, wiki syntax or style improvements. See Help:Style for reference.

Reason: Use absolute paths, as currently it is not clear where exactly should the directory be located. Also, chown can set user and group ownership in one command. (Discuss in Talk:SpamAssassin#)

Create a spamassassin directory in /etc/mail and change the owner and group

    # mkdir /etc/mail/spamassassin/sa-update-keys
    # chown spamd:spamd /etc/mail/spamassassin/sa-update-keys
    # chmod 700 /etc/mail/spamassassin/sa-update-keys

Next start and enable `spamassassin.service`.

## Usage

Go over `/etc/mail/spamassassin/local.cf` and configure it to your needs.

### Updating rules

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`.

## Plugins

### ClamAV

Install and setup clamd as described in ClamAV.

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

Install the perl-cpanplus-dist-arch 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 `/etc/mail/spamassassin/`. Edit `/etc/mail/spamassassin/clamav.pm` and update `$CLAMD_SOCK` to point to your Clamd socket location (default is `/run/clamav/clamd.ctl`).

Finally, restart `spamassassin.service`.

### Razor

Note: The last version was released 2008.[1]

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

Make sure you have installed SpamAssassin first, then:

Install the razor 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 `/etc/mail/spamassassin/razor/razor-agent.conf`:

     razorhome = /etc/mail/spamassassin/razor/

Finally, restart `spamassassin.service`.
