Rspamd

Introduction

Rspamd is an advanced spam filtering system supporting a variety of filtering mechanisms 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.

More about Rpamd can be read here https://rspamd.com/about.html.

Implementation

Before implementing the SPFBL.net configuration for your Rspamd, make sure that your email service does not exceed the limit of 10 queries per second in our services. Usually this does not occur, but if you think this is possible, consider a monthly donation to the project and then we can increase the threshold according to the amount donated. In case your email service exceeds the established limit, whatever it may be, this service may be temporarily banned from all our public services.

You can implement all SPFBL.net services in your Rspamd by downloading the file spfbl-rspamd-config- 1.0.tar and following these steps:

1. Make a backup of your directory /etc/rspamd

tar -czf /root/backup-rspamd.tar.gz /etc/rspamd

2. Untar the file spfbl-rspamd-config-1.0.tar.gz

tar -C / -xzf /path/to/spfbl-rspamd-config-1.0.tar.gz

3. Restart the rspamd service.

Or, you can also implement manually all SPFBL.net services in your Rspamd by following these sample source codes:
