Mailcow vs docker-mailserver: Self-Hosted Email Compared

Running your own email server? Mailcow gives you a full web UI and webmail, while docker-mailserver keeps it to a single lightweight container. Here's how to choose. Quick Verdict Mailcow is better for users who want a full-featured web interface with webmail, admin panel, and user self-service. docker-mailserver is better for sysadmins who want a lightweight, CLI-managed mail server with minimal resource usage.

Mailcow bundles everything (Postfix, Dovecot, SOGo webmail, admin panel, ClamAV, Rspamd) into a multi-container stack with a polished web UI. docker-mailserver runs everything in a single container with no web interface — all management happens through CLI commands.
