Parent article: A look at Rspamd

I've used SpamAssassin on a small-to-medium mail system (hundreds of users) for many years and I've been quite happy with it. But in the last two years or so, the amount of spam getting through has increased and despite some effort to fine-tune the setup, I haven't been able to improve the situation much.

I'm wondering if there's any experience about the accuracy of Rspamd vs. SpamAssassin. Of course a lot depends on the circumstances, but it should still be possible to perform a study comparing relative accuracy on a sufficiently large classified corpus of spam and non-spam. With some quick searching I couldn't find any, but maybe I didn't look hard enough.

Any experience of how well Rspamd detects spam? I'm not so concerned about server resources and such, they have never been a problem with SpamAssassin for me.

The main problem is that the spammers route their spam through SpamAssassin themselves and make small changes here and there until the score is low enough and then they send it.

If you own the incoming gateway, maybe you could mirror the mail to Rspamd while still using SpamAssassin and look at the cases where SpamAssassin and Rspamd disagree. This is basically what AOL Mail does to evaluate spam filter changes, but I also don't know how much work it was to set up.
