Your Email, Your Rules: Self-Hosting Simplified
Jonathan Haack

In an era where data privacy and security are paramount, self-hosting an email server offers unmatched control, customization, and protection from third-party surveillance. "Your Email, Your Rules: Self-Hosting Simplified" empowers Debian GNU/Linux users by dispelling myths that self-hosting email is overly complex or impractical. Key topics include privacy through data ownership, server/VPS hardening, DNS records, server policies, autodiscovery, encrypted transmission and content, spam management with sieve, and Roundcube webmail. The presentation concludes by delimiting the approach’s scope and provides a roadmap for adjustments needed to scale to larger use cases.
