NNCPNET: Reclaiming Email's Tinkering Spirit

From 1995 to 2019, the author self-hosted email, evolving from UUCP to VPS. But modern email complexities (SPF, DKIM, DMARC, TLS) made it increasingly difficult. Enter NNCPNET, an email system built on top of NNCP, a secure, asynchronous, onion-routed network. Like SSH to Telnet, NNCP modernizes email transport. NNCPNET offers a Docker container (multi-arch, Raspberry Pi compatible) with Exim, NNCP, verification tools, and automated nodelist updates. It's easy to set up, requires no inbound ports or constant internet connection, and even integrates with Thunderbird via IMAP. Reclaim the joy of email experimentation!
