An advanced spam filtering system and email processing framework that evaluates messages using regex, statistical analysis, and custom services.
Rspamd is an advanced spam filtering system and email processing framework that evaluates email messages using multiple methods including regular expressions, statistical analysis, and custom services like URL blacklists. It provides real-time verdicts to help mail transfer agents (MTAs) reject spam, flag suspicious messages, and handle tasks like DKIM signature verification.
System administrators, email server operators, and organizations managing their own mail infrastructure who need robust, scalable spam filtering integrated with MTAs like Postfix or Sendmail.
Developers choose Rspamd for its high performance, extensibility through Lua scripting, seamless integration with popular MTAs via Milter, and comprehensive built-in filtering modules that work out of the box.

Designed to process hundreds of messages per second simultaneously, ensuring efficient resource usage for high-volume email servers, as stated in the README.
Acts as a Milter to directly interact with popular MTAs like Postfix and Sendmail, simplifying deployment in existing email infrastructures, per the README's integration focus.
Provides a comprehensive Lua API for writing custom rules and plugins, allowing deep customization of spam filtering logic, as highlighted in the documentation links.
Comes with various pre-configured spam filtering modules ready out of the box, reducing initial setup time, as mentioned in the spam filtering features section.
Requires careful configuration and understanding of email systems, evidenced by the need for a quick start guide and warnings against outdated OS packages in the README.
Heavy reliance on Lua scripting for advanced features can be a barrier for teams without prior experience, increasing the learning curve beyond basic administration.
Custom Lua rules and external modules can lead to complex, hard-to-manage configurations over time, with the README advising against using unsupported distributive packages.
