Mox

Modern full-featured open source secure mail server

Mox is a modern email server implementation that makes it easy for people and organizations to run their own mail server, allowing them to stay in control of their own email communication, and keeping email decentralized. While high-quality open source mail server software components exist, their code bases are growing old, and getting a working setup involves configuring at least half a dozen of them to work together. That complexity has turned people to a few (centralized) email providers. Mox gives users their power back! All important protocols/mechanisms needed for a modern email setup have been implemented in mox, including: IMAP4, SMTP, SPF, DKIM, DMARC, MTA-STS, TLSRPT, automatic TLS with ACME and Let's Encrypt, IP/domain/bayesian spam filtering, internationalized email, account autoconfiguration. Setting up mox takes just minutes with the quickstart, with no additional tools/dependencies required. The code base is lean, coherent, self-contained, well-tested, cross-referenced with specifications, liberally MIT-licensed, trivially reproducibly built and is defensively written in Go, a modern, safe programming language. Mox's integrated approach has allowed for novel functionality. Development continues on supporting more protocols and extensions, as well as quality improvements such as more automated tests. On the roadmap at the time of writing (but check the project site!): IMAP4 CONDSTORE, QRESYNC, THREAD extensions, DANE and DNSSEC, sending DMARC and TLS reports, OAUTH2, Sieve, JMAP, Webmail, Calendaring and more.
