Rspamd Integration for Eenos as a SpamAssassin Alternative

I would like to request native Rspamd integration in Eenos as an alternative to SpamAssassin for email spam filtering.

Rspamd is a modern, high-performance spam filtering system that supports advanced spam detection, reputation checks, Redis integration, and machine learning based filtering.

It would be great if Eenos could offer both SpamAssassin and Rspamd, allowing server administrators to choose their preferred spam filtering engine.

Suggested Features

• Spam Filtering Engine Selection: Allow administrators to choose between SpamAssassin and Rspamd from the Eenos Mail Server settings.

• Native Exim Integration: Integrate Rspamd with the existing Exim mail server using its supported spam filtering interfaces.

• Automatic Installation and Configuration: Provide a simple interface to install, configure, enable, disable, and manage Rspamd.

• Redis Support: Support Redis for caching, statistics, reputation data, and Bayesian learning.

• Spam Detection Settings: Configure spam score thresholds, rejection policies, and spam header tagging.

• Bayesian Filtering: Support automatic spam and ham learning to improve spam detection.

• RBL and DNSBL Support: Allow configuration of DNS based reputation and blocklists.

• DKIM, SPF and DMARC Checks: Integrate authentication results into spam filtering decisions.

• Per Domain Spam Settings: Allow hosting users to configure supported spam filtering preferences for their domains.

• Rspamd Web Interface: Provide access to Rspamd statistics, filtering history, and configuration through the Eenos administration interface.

• SpamAssassin Migration: Provide a supported way to switch filtering engines without disrupting existing email services.

• Performance Monitoring: Display filtering statistics, processing times, and resource usage.

Why Is This Feature Important?

SpamAssassin is a well-established spam filtering solution, but Rspamd offers an alternative architecture designed for efficient, high-volume email processing.

Providing Rspamd as an optional spam filtering engine would give hosting providers more flexibility to optimize email security, spam detection, and server resource usage.

This would be especially useful for shared hosting providers managing large numbers of email accounts and domains.

I hope the Eenos development team will consider adding native Rspamd integration while continuing to support SpamAssassin.
