You Against the Email Empire. Message services appear and disappear, but email remains. One of the Internet's oldest and most open protocols, email reaches everywhere. Dominated by a handful of carriers, yet still manageable by the rest of us. If you do it right. Setting up the email server is the easy part. The protocols that support email? Those are hard. SPF. DKIM. DMARC. BIMI and MTA-TLS and TLS-RPT. DNS standards that apply to nothing else on the modern Internet. Block lists. Graylisting. Email is a protocol unlike any other, yet among our most essential. This is a book for beginning email operators, but it’s not a book for a beginner sysadmin. You must know how to manage your operating system. You need to back up your hosts, apply security updates, know the difference between network and local sockets, and in general make your hosts fit to sit on the naked Internet. This book assumes and recommends open-source software. I demonstrate everything with Postfix running on FreeBSD or Debian Linux.
