Mox is an all-in-one email server focused on being easier to run and safer by default than traditional “glue-it-together” mail stacks. It provides SMTP submission/receiving and IMAP access, a built-in admin web interface, and sensible defaults for modern email authentication and deliverability.

Key Features

  • Integrated SMTP server (incoming + submission) and IMAP server
  • Built-in admin web UI for managing domains, accounts, and operational settings
  • Automatic TLS certificate provisioning via ACME
  • Modern email authentication and policy support (DKIM signing, SPF/DMARC evaluation)
  • Spam filtering controls (including common DNSBL-style checks) and delivery safeguards
  • Mailbox storage and indexing handled by Mox (no external IMAP/SMTP components required)
  • Operational tooling for diagnostics/logging and safer configuration changes

Use Cases

  • Host email for a personal domain or small organization with a single, cohesive server
  • Replace a multi-component Postfix/Dovecot stack with an integrated setup
  • Run a mail server with modern authentication defaults for better deliverability

Limitations and Considerations

  • Not a full groupware suite (no calendars/contacts as a primary feature)
  • Self-hosted email deliverability depends on correct DNS and IP reputation

Mox aims to reduce complexity by shipping a cohesive mail server with an admin UI and modern defaults. It’s best suited for operators who want a straightforward, integrated email stack while retaining control over their domains and accounts.
