We are thrilled to announce the release of Stalwart Mail Server 0.5.2, which brings two significant advancements: the integration of the ACME protocol for automatic TLS certificate deployment and support for the HAProxy Protocol. These features mark a substantial step forward in our commitment to enhancing the security and efficiency of Stalwart Mail Server.
Not even saying that. Mailcow-dockerized is as simple to set up but separates the functions by container, and lets you specify secrets for database access, etc outside the docker compose. Unfortunately, the other easy-to-set-up one, docker-mailserver is a monolithic container as well.
I would also point out that people that don’t understand server security practices should probably stay way the hell away from self-hosting mail. When I did this professionally, I would compartmentalize the mail infra physically, then eventually by individual VMs. I now use unprivileged docker on it’s own docker host separate from the rest of my infra, in fact on another virtualized DMZ, because mail is the #2 point of contact for penetration.
