# Plesk

To add Guardian Mail:

In the Plesk console, go to “Tools & Settings” and “Mail Server Settings” under the “Mail” heading.

Scroll to the bottom of the page and enable the option “Turn on [spam](https://abusix.com/glossary/spam/) protection based on [DNS](https://abusix.com/glossary/domain-name-system/) blackhole lists,” then set “[DNS](https://abusix.com/glossary/domain-name-system/) zones for [DNSBL](https://abusix.com/glossary/domain-name-system-blocklist/) service” to:

\<APIKEY>.[combined.mail.abusix.zone](http://combined.mail.abusix.zone)

Replace \<APIKEY> with “**Your API key”** from your account in [app.abusix.com](http://app.abusix.com).

Then click ‘OK.’

SpamAssassin can also be installed on Plesk, allowing Guardian Mail to provide additional filtering.

This can be installed by going to “Tools & Settings,” “Plesk,” “Updates,” “Add/Remove Components”, expanding “Mail Hosting” by clicking the + next to it, selecting “Install” under “SpamAssassin” and click “Continue.”

Once SpamAssassin is installed, you can use the following instructions to configure it to use Guardian Mail. You will need to use [SSH](https://abusix.com/glossary/secure-shell-protocol/) and edit the necessary files by hand, as Plesk does not provide a way to do this via the console.

**Instructions**

Edit [*local.cf*](http://local.cf)\_ \_(usually found in /etc/mail/spamassassin) as follows.

```
ifplugin Mail::SpamAssassin::Plugin::DNSEval
    header    __RCVD_IN_AMI       eval:check_rbl('ami', '<APIKEY>.combined.mail.abusix.zone.')
    describe  __RCVD_IN_AMI       Received via a relay in Guardian Mail
    tflags    __RCVD_IN_AMI       net

    header    RCVD_IN_AMI_BLACK   eval:check_rbl_sub('ami', '^127\.0\.0\.(?:[23]|200)$')

    tflags    RCVD_IN_AMI_BLACK   net

    describe  RCVD_IN_AMI_DYN     Received via a relay in Guardian Mail Dynamic
    score     RCVD_IN_AMI_DYN     3.0
    tflags    RCVD_IN_AMI_DYN     net

    header    RCVD_IN_AMI_WHITE   eval:check_rbl('ami-firsttrusted', '<APIKEY>.combined.mail.abusix.zone.', '127.0.2.1')
    describe  RCVD_IN_AMI_WHITE   Received via a relay in Guardian Mail White
    score     RCVD_IN_AMI_WHITE   -0.1
    tflags    RCVD_IN_AMI_WHITE   nice net
endif

ifplugin Mail::SpamAssassin::Plugin::URIDNSBL
    urirhsbl  URIBL_AMI_DBLACK    <APIKEY>.dblack.mail.abusix.zone. A
    body      URIBL_AMI_DBLACK    eval:check_uridnsbl('URIBL_AMI_DBLACK')
    describe  URIBL_AMI_DBLACK    Contains a spam URL listed in the Guardian Mail domain blocklist
    score     URIBL_AMI_DBLACK    3.0
    tflags    URIBL_AMI_DBLACK    net

    urirhssub URIBL_AMI_WHITE     <APIKEY>.white.mail.abusix.zone. A 127.0.2.1
    body      URIBL_AMI_WHITE     eval:check_uridnsbl('URIBL_AMI_WHITE')
    describe  URIBL_AMI_WHITE     Contains a domain listed in the Guardian Mail domain whitelist
    score     URIBL_AMI_WHITE     -0.1
    tflags    URIBL_AMI_WHITE     nice net
endif
```

Replace \<APIKEY> in all places with “**Your API key”** from your account in [app.abusix.com](http://app.abusix.com).

Then restart SpamAssassin.

Once you have made these changes, run “systemctl restart spamassassin” to restart it.
