I know DirectAdmin supports Rspamd spam filtering system. How to install it on a Linux server with the control panel?

Introduction

Rspamd is an advanced spam filtering system that allows evaluation of messages by a number of rules including regular expressions, statistical analysis and custom services such as URL black lists. Each message is analysed by Rspamd and given a spam score.

According to this spam score and the user’s settings, Rspamd recommends an action for the MTA to apply to the message, for example, to pass, reject or add a header. Rspamd is designed to process hundreds of messages per second simultaneously, and provides a number of useful features.

Requirements: 

Here is a list of basic requirements which your server should meet for the filtering system to work:

  • DirectAdmin Version 1.56.0 or higher
  • CentOS
  • Exim 
  • EasySpamFighter 1.17+
  • exim.conf 4.5+

If it's all OK then we proceed with an installation.

Installation on DirectAdmin server

Connect as root to your server console and run the following commands to let CustomBuild do it for you.

cd /usr/local/directadmin/custombuild
./build update
./build set eximconf yes
./build set eximconf_release 4.5
./build set blockcracking yes
./build set easy_spam_fighter yes
./build set spamd rspamd
./build set exim yes
./build exim
./build rspamd
./build exim_conf

Run the commands one-by-one and make sure no error occurs. If any command ends with an error, you should first fix it and then only process remaining.

The command ./build rspamd is expected to finish with the following lines on CentOS 7:

[root@good custombuild]#


As it's compiled into binary code, it should run much faster than SpamAssassin, and use fewer resources.

Check the logs under /var/log/rspamd/rspamd.log for details to see how it runs.
