## Project history and usage

Mox is an all-in-one mail server project whose site says work started in 2021 in response to email administration becoming concentrated around large cloud and hosting providers and to the operational burden of assembling many separate mail components. The project frames that burden as both usability and safety work: modern email requires SMTP, IMAP, authentication, TLS, DNS records, filtering, and policy protocols, often spread across several daemons.

### Project history

Mox's major technical milestone is its integrated design. The README describes one secure mail server for low-maintenance self-hosted email, with SMTP for receiving, submission, and delivery; IMAP4 for mail clients; webmail; SPF, DKIM, and DMARC; DMARC aggregate reports; reputation tracking; junk filtering; and setup flows that print the DNS records an administrator must add. The project site also describes a quickstart path and a `mox localserve` mode for local SMTP, IMAP, and webmail testing without a full public-domain setup.

### How it is used

In package-manager terms, Mox competes less with a single package than with stacks such as Postfix plus Dovecot plus filtering and policy tools. Its appeal is to self-hosters and small-domain administrators who want one Go program, one configuration model, and built-in modern mail hygiene instead of composing a mail system from many long-lived Unix services.
