Rspamd
Rspamd has been started to handle mail flows that has grown over the last decade by more than ten times. From the very beginning of the project, Rspamd was oriented on highly loaded mail systems with development focus on performance and scan speed. Rspamd is written in plain C language and it uses a number of techniques to run fast especially on the modern hardware. On the other hand, it is possible to run Rspamd even on an embedded device with a very constrained environment. You can also check the recent performance analyze article to have a better impression about how fast Rspamd could be. Rspamd can be treated as a faster replacement for SpamAssassin mail filter with the ability to scan ten times more messages using the same rules (by means of SpamAssassin plugin). In the next graph, you can see how switch to Rspamd from SA helped to reduce CPU load on scanner machines. Rspamd can work with the most popular mail transfer systems, such as Postfix, Exim, Sendmail or Haraka.
