spamscanner

Spam Scanner is a tool and service created after hitting countless roadblocks with existing spam-detection solutions. In other words, it's our current plan for spam.

Our goal is to build and utilize a scalable, performant, simple, easy to maintain, and powerful API for use in our service at Forward Email to limit spam and provide other measures to prevent attacks on our users.

Initially we tried using SpamAssassin, and later evaluated rspamd – but in the end we learned that all existing solutions (even ones besides these) are overtly complex, missing required features or documentation, incredibly challenging to configure; high-barrier to entry, or have proprietary storage backends (that could store and read your messages without your consent) that limit our scalability.

To us, we value privacy and the security of our data and users – specifically we have a "Zero-Tolerance Policy" on storing logs or metadata of any kind, whatsoever (see our Privacy Policy for more on that). None of these solutions honored this privacy policy (without removing essential spam-detection functionality), so we had to create our own tool – thus "Spam Scanner" was born.

The solution we created provides several Features and is completely configurable to your liking. You can learn more about the actual Algorithm below. Contributors are welcome.

Spam Scanner includes modern, essential, and performant features that to help reduce spam, phishing, and executable attacks.
