Getting Started – Abusix

Introduction

Exim

To add Abusix Mail Intelligence

Single configuration file

If you are using a single configuration file, open exim.conf and find the "acl_check_rcpt:" section, and add:

deny message = $dnslist_text
dnslists = <APIKEY>.combined.mail.abusix.zone

Replace <APIKEY> with “Your API key” from your account in app.abusix.com.

Then restart Exim.

Split configuration file

If you are using Exim split configuration, then open /etc/exim4/conf.d/acl/30_exim4-config_check_rcpt and find the “.ifdef CHECK_RCPT_IP_DNSBLS” section and add the following after the “.endif”:

deny
    dnslists = <APIKEY>.combined.mail.abusix.zone
    add_header = X-Warning: $sender_host_address is listed by Abusix ($dnslist_value: $dnslist_text)
    log_message = $sender_host_address is listed by Abusix\n$dnslist_text

Replace <APIKEY> with “Your API key” from your account in app.abusix.com.

Then restart Exim.

Microsoft Exchange

To add Abusix Mail Intelligence

Add the following code below as described in the following Microsoft Support Documentation:

Add-IPBlockListProvider -Name "Abusix" -LookupDomain <APIKEY>.combined.mail.abusix.zone -RejectionResponse "Source IP address is listed by Abusix Mail Intelligence" -AnyMatch $true

Replace “APIKEY” with “Your API key” from your account in app.abusix.com.

Qmail

To add Abusix Mail Intelligence

Edit your /var/qmail/supervise/qmail-smtpd/run file, adding "-r" or "-a" to the configuration file so that rblsmtpd runs before Qmail.

Create a run file using the following sample code.

exec
    /usr/local/bin/softlimit -m 30000000 \
    /usr/local/bin/tcpserver -v -H -R -l 0 -x /etc/tcp.smtp.cdb -c MAX-SMTP-CONNS -u QMAIL-USER -g QMAIL-GROUP 0 smtp \
        /usr/local/bin/rblsmtpd -t 5 \
            -b -r <APIKEY>.combined.mail.abusix.zone \
        /var/qmail/bin/qmail-smtpd 2>&1

Replace <APIKEY> with “Your API key” from your account in app.abusix.com.

Postfix

There are various ways to configure Postfix with Abusix Mail Intelligence. The following is our preferred method.

Edit /etc/postfix/main.cf

Add the following in the "smtpd_recipient_restrictions" parameter. It should be placed after "reject_unauth_destination".

smtpd_recipient_restrictions =
    ...
    reject_unauth_destination
    # Check rDNS in domain blacklist (optional)
    reject_rhsbl_client <APIKEY>.dblack.mail.abusix.zone
    # Check HELO/EHLO in domain blacklist (optional)
    reject_rhsbl_helo <APIKEY>.dblack.mail.abusix.zone
    # Check FROM domain in blacklist (optional)
    reject_rhsbl_sender <APIKEY>.dblack.mail.abusix.zone
    # Check connecting IP in whitelist (optional)
    # permit_dnswl_client entries should be placed before any reject directives
    # that want to skip, but should always be before any reject_rbl_client
    # entries to ensure that any IP listed on the whitelist not rejected.
    permit_dnswl_client <APIKEY>.white.mail.abusix.zone
    # Reject any IP listed in the blacklist
    reject_rbl_client <APIKEY>.combined.mail.abusix.zone

rbl_reply_maps = texthash:/etc/postfix/rbl_reply_map

Replace <APIKEY> with “Your API key” from your account in app.abusix.com.

Next, to prevent your API key from being leaked, create /etc/postfix/rbl_reply_map with the following:

<APIKEY>.combined.mail.abusix.zone        $rbl_code Service unavailable; $rbl_class [$rbl_what] blocked using Abusix Mail Intelligence${rbl_reason?; $rbl_reason}
<APIKEY>.dblack.mail.abusix.zone        $rbl_code Service unavailable; $rbl_class [$rbl_what] blocked using Abusix Mail Intelligence${rbl_reason?; $rbl_reason}

Replace <APIKEY> with “Your API key” from your account in app.abusix.com.

If you are using Postscreen, you can omit the "reject_rbl_client" entry and instead add:

postscreen_dnsbl_reply_map = texthash:/etc/postfix/postscreen_dnsbl_reply_map
postscreen_dnsbl_sites = <APIKEY>.combined.mail.abusix.zone

Replace <APIKEY> with “Your API key” from your account in app.abusix.com.

Then to prevent your API key from leaking, create /etc/postfix/postscreen_dnsbl_reply_map, which should contain the following:

<APIKEY>.combined.mail.abusix.zone                mail.abusix.zone

Replace <APIKEY> with “Your API key” from your account in app.abusix.com.

Then reload Postfix to activate this configuration.

Sendmail

To add Abusix Mail Intelligence

Edit your sendmail.mc file (usually found in /etc/mail) and add the following:

FEATURE(`dnsbl',`<APIKEY>.combined.mail.abusix.zone',`"554 Rejected " $&{client_addr} " is listed by Abusix Mail Intelligence see http://abusix.ai/search?q="$&{client_addr}')dnl

Replace <APIKEY> with “Your API key” from your account in app.abusix.com.

Compile sendmail.mc by running “make” in the same directory and then restart the Sendmail daemon.

SpamAssassin

To add Abusix Mail Intelligence

Edit 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.')

    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 Abusix Mail Intelligence domain blocklist

    tflags    URIBL_AMI_WHITE     nice net
endif

Replace “APIKEY” in all places with “Your API key” from your account in app.abusix.com.

Then restart SpamAssassin.

Rspamd

To add Abusix Mail Intelligence

Updated: 2022-12-13

⚠️

These instructions are for rspamd 3.x - if you aren’t running the latest version, you should be! You wouldn’t use an out-of-date Anti-Virus engine, so don’t run an out-of-date Anti-Spam engine.

You need to edit the following files (or create them if they don't already exist).

/etc/rspamd/local.d/rbl.conf

rbls {
    abusix_dnsbls_lasthop {

Barracuda Email Firewall

To add Abusix Mail Intelligence

Go to BLOCK/ACCEPT -> IP Reputation in Barracuda, and under Custom External RBLs, add:

<APIKEY>.combined.mail.abusix.zone

Replace <APIKEY> with “Your API key” from your account in app.abusix.com.

And select "BLOCK.”

Example

Once set up, you will see "Blocked" items in the Message Log, and within those, the messages that Abusix Mail Intelligence blocked.

Example

Symantec Email Gateway

To add Abusix Mail Intelligence

In the Symantec Email Gateway appliance, in the Control Center, go to Reputation -> Bad Senders, ensure that 'Enable Third-Party Bad Sender detection' is enabled, click 'Add', and enter:

<APIKEY>.combined.mail.abusix.zone.

Replace <APIKEY> with “Your API key” from your account in app.abusix.com.

Please make sure the Action is set to 'Reject SMTP Connection' and then click 'Save.’

Plesk

To add Abusix Mail Intelligence

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 protection based on DNS blackhole lists,” then set "DNS zones for DNSBL service" to:

<APIKEY>.combined.mail.abusix.zone

Replace <APIKEY> with “Your API key” from your account in app.abusix.com.

Then click 'OK.'

SpamAssassin can also be installed on Plesk, allowing Abusix Mail Intelligence 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 Abusix Mail Intelligence. You will need to use SSH and edit the necessary files by hand, as Plesk does not provide a way to do this via the console.

Instructions

Edit local.cf (usually found in /etc/mail/spamassassin) as follows.
