Along the way, we unpack the protocols and systems that make modern email work, from SMTP, IMAP, SPF, DKIM, and DMARC to certificate automation, Docker deployment, S3-backed storage, LDAP integration, and observability with Prometheus metrics. The episode also looks at why Maddy’s Go-based architecture matters, how its composable design balances beginner-friendly defaults with advanced flexibility, and what it could mean for the future of decentralized communication if secure self-hosted email becomes genuinely accessible again.
