Docker Mailserver is a full‐stack, production-ready mail server packaged to run inside a container. It provides SMTP, IMAP, POP3, LDAP support, antispam, antivirus, DKIM/DMARC/SPF etc., and it's intended to be simple to configure: mostly via configuration files, environment variables, and volume mounts. It does not rely on an SQL database by default. It offers good security defaults and is suitable for deployment in Docker, Kubernetes, or equivalent containerized environments.

Features

  • Support for SMTP, IMAP, POP3, LDAP authentication and user management
  • Integrated antispam & antivirus tools (Rspamd, SpamAssassin, ClamAV, etc.)
  • Easy configuration via environment variables and overrideable config files in container volumes
  • No SQL database requirement by default; simpler versioned configs and fewer moving parts
  • Supports modern email authentication and deliverability standards: DKIM, DMARC, SPF, TLS etc.
  • Extensible with LDAP, fetchmail/getmail for mail retrieval, optional features like quotas, sieve filters etc.
