v0.9.4 · 19.8 MB

A single binary combining SMTP, IMAP, DKIM, SPF, DMARC, DANE, MTA-STS to replace Postfix, Dovecot, etc.

Core Features

  • Combines SMTP MTA, IMAP storage, DKIM, SPF, DMARC, DANE, MTA-STS in one daemon
  • Single configuration file, no multiple software integration
  • Minimal maintenance and reduced attack surface
  • Lightweight compared to traditional multi-component stacks

What It Can't Do

  • •IMAP storage is in beta – do not rely on it for critical mail storage in production. Consider using Dovecot for storage if stability is required. Maddy does not include a webmail client; use third-party solutions like Roundcube.

Use Cases

  • Self-hosted email for individuals or small teams
  • Secure mail infrastructure requiring minimal overhead
  • Migrating from complex Postfix/Dovecot setups to a unified solution

Maddy Mail Server bundles SMTP (MTA), IMAP storage, DKIM, SPF, DMARC, DANE, and MTA-STS into one binary. It simplifies email server setup and maintenance by eliminating the need to install and configure multiple tools. The IMAP storage is still in beta, so users requiring rock-solid mail storage may prefer Dovecot. Maddy excels in ease of use and reduced attack surface, making it ideal for small to medium deployments or hobbyists who want a modern mail stack without the complexity.
