    Project mention: Ask HN: Spammers got smarter or Gmail is no longer good? | news.ycombinator.com | 2022-01-25

    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.
