AgentJ: sovereignty score and 8 European alternatives

AgentJ is a free anti-spam system for mail servers built around human verification: when an unknown sender writes for the first time, they receive a confirmation email to show they are not a machine. AgentJ also filters inbound and outbound mail for spam and viruses and limits the damage from compromised accounts. It runs as a Docker stack using components such as Postfix, SpamAssassin, ClamAV and OpenDKIM, with a web interface for administration, quotas, whitelists and statistics. It is delivered as server software that you install yourself.

AgentJ is a project of Probesys, a French cooperative company (SARL SCOP) in Grenoble, and is released under the AGPL-3.0; the source code is on GitHub. You can run it yourself, or have Probesys install it on your own servers with support. Probesys also offers a hosted instance which, according to its website, runs in Grenoble. When you self-host, your mail traffic stays on your own infrastructure.

Why digital sovereignty matters with AgentJ

AgentJ is headquartered in FR and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so AgentJ scores best on data residency.

AgentJ is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs AgentJ together with your other vendors and gives a total score, a heatmap and the main risk drivers.
