mailcow: dockerized is an open-source, Docker-based groupware and email suite that combines Postfix, Dovecot, Rspamd, SOGo webmail, ClamAV, and a graphical mailcow UI for administering domains, mailboxes, TLS policies, and anti-abuse settings.
Administrators who prefer a containerized all-in-one mail and groupware stack with a web UI instead of assembling Postfix and Dovecot manually.
You provide Docker hosts, volumes, and DNS; misconfigured volumes or missing backups can lose mail data as warned in official docs.
mailcow bundles antispam, antivirus, webmail, and administration tools so operators can run a production mail platform on Docker with ACME-managed certificates.
