Same problem as well; there are so many attack vectors it's absurd.
I've tried rspamd, SpamAssassin, and so many other alternatives. Then I decided to try writing my own in JS.
Spam Scanner (work in progress) is at https://spamscanner.net with source code at https://github.com/spamscanner. Trying to do it in a privacy-focused way, which is incredibly challenging to say the least.
Fortunately we're thinking that with ARF in combination with human curators (privacy-focused where sensitive data is redacted during curation process), and a combination of tech - will make this at least a bit better - and completely open source too.
We're in the progress of building an SMTP alternative, so we're not just a forwarding service (Forward Email at https://forwardemail.net) - and I hope to have Spam Scanner hooked in to individual inboxes as well, so it gets smarter for the individual users as opposed to group-think.
I'm hoping that we can at least make things a bit smarter with some scrappy measures over time. Hoping to launch SMTP by April so you can use Thunderbird, Apple Mail, or K-9 for instance with your own inbox running Spam Scanner.
Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.
