I'm running a Enhance -powered mail server in my stack, and I've been struggling with spam not being adequately caught by Rspamd. While Rspamd is integrated within Enhance, I’ve noticed that the default configuration seems quite basic and doesn’t catch enough spam.
I’m looking for advice from others who have fine-tuned their spam filtering settings. Specifically, I’d love to hear about any custom configurations, module recommendations (like RBLs, Bayesian filtering, fuzzy checks), or any other tips that have helped improve spam detection.
I know there has been talks about improvements in future upgrades of Enhance, but I am not sure I can wait that long without loosing customers to their daily frustration of spam being let through, without any proper means of filtering their mail.
