As of 2023/2024 mail is still one of the most important attack vectors for Ransomware, Spam or Phishing.

The commercial vendors of mail security products show off using many advanced buzzwords to advertise their features. It seems they have magic algorithms to catch every threat. And you can only buy it in their shop.

Is there any chance to build a mail security platform with open-source components on-prem that is at least as effective??

With the help of a robust MTA infrastructure and the excellent anti-spam solution and mail-framework Rspamd we would like to show you that most of the buzzword ideas are covered by Rspamd or could be queried by Rspamd.

All we need is good reputation data - selfmade, commercial or from the community.

Let's have a look if we can compete with commercial vendors and build up an Enterprise Mail Security using open-source.
