mailcow: dockerized is a full-featured, self-hosted mail server suite delivered as a set of Docker containers, bundling Postfix, Dovecot, SOGo, Rspamd, ClamAV, ACME, and an admin web UI. It provides email hosting with groupware features, spam filtering, and TLS certificate management out of the box.

Use cases

• self-host a complete email server with docker
• run a mailserver with webmail and groupware
• host email for multiple domains with an admin UI
• set up SMTP and IMAP with spam filtering
• deploy a mail server with automatic TLS certificates
• replace hosted email with an on-premise mail stack

When to choose

• you want a batteries-included mail server (MTA, IMAP, webmail, antispam, antivirus) managed via docker-compose
• you need groupware features like calendars and contacts via SOGo alongside email
• you want automatic Let's Encrypt certificates and a polished admin web UI
• you prefer a well-maintained suite with frequent security updates

When to avoid

• you only need a lightweight SMTP relay or single-purpose MTA rather than a full suite
• you cannot run Docker or dedicate a server with proper ports and reverse DNS for email
• you want to assemble your own mail stack from individual components
• you need a mail server for very resource-constrained hardware
