Spamassassin or rspamd or ASSP. All very good. Spamassassin just works, but you need to feed it a good cohort of spam and ham (about 1000 messages each). Most people only send it the spam which will then bias it quite a bit and not have it classify spam as spam unless it's the worst of the bunch. Spamassassin is a filter for your mail server. Rspamd is the same idea. ASSP is highly configurable and a proxy. Source: 11 months ago

Definitely. I think Gmail spam filtering has just gone haywire with way too much input, ChatGPT style sales pitches, and too much clutter. At Skiff (https://skiff.com/mail), we use RSPAMD (https://rspamd.com/), an open-source spam filtering framework. It's not as sophisticated, but it is highly explainable and works consistently. I much prefer this + inbox rules to anything else. - Source: Hacker News / over 1 year ago
When I installed Rspamd with on OpenBSD / OpenSMTPD the other day, DKIMProxy out (dkimproxy_out daemon), which had been got via OpenBSD Ports package system, was used to add DKIM signatures to mails in order to improve security on emails. - Source: dev.to / almost 3 years ago
Well, Rspamd includes web interface to monitor its performance. I combined it with relayd. - Source: dev.to / almost 3 years ago
