Rspamd was developed to manage the significant increase in mail flows over the past decade, which has surged by more than tenfold. From its inception, the project has targeted high-traffic mail systems, prioritizing speed and performance in its development. Written in the C programming language, Rspamd employs various methods to ensure rapid operation, particularly on contemporary hardware. Remarkably, it can also function effectively on embedded devices with limited resources. For a clearer understanding of its impressive speed, you can refer to a recent performance analysis article. Rspamd serves as a more efficient alternative to the SpamAssassin mail filter, capable of scanning ten times the number of messages with the same set of rules through the use of a SpamAssassin plugin. A graph illustrating the transition from SpamAssassin to Rspamd demonstrates a notable reduction in CPU load on scanning machines. Additionally, Rspamd is compatible with well-known mail transfer agents, including Postfix, Exim, Sendmail, and Haraka, making it a versatile choice for various email systems. This flexibility in compatibility allows organizations to seamlessly integrate Rspamd into their existing infrastructure.
