About Spam Scanner
Spam Scanner is a powerful anti spam, email filtering and phishing defense service platform. Spam Scanner is also the best alternative to SpamAssassin, rspamd, SpamTitan and other products.
Our goal is to establish and utilize a scalable, high-performance, simple, easy to maintain and powerful API for our forwarding e-mail service to limit spam and provide other measures to prevent cyber criminals from attacking our users.
At first, we tried to use SpamAssassin, and then evaluated rspamd, but in the end, we found that all existing solutions are very complex, lack the required functions or documents, troublesome to configure, high technical barriers, and limit the scalability of the platform from other perspectives.
For us, we value privacy and the security of data and users - in particular, we have a "zero tolerance policy" for storing any type of log or metadata. None of these solutions comply with this Privacy Policy (without deleting the basic spam detection function), so Spam Scanner came into being.
