## What it is
A production-ready, containerized fullstack mail server bundling Postfix (SMTP), Dovecot (IMAP/POP3), Rspamd, SpamAssassin, ClamAV, Fail2ban, and optional LDAP support. It is configured entirely through versioned configuration files with no SQL database, deployable via Docker Compose or Kubernetes.

## Use cases
- self-host a complete email server in docker
- run smtp and imap server with antispam and antivirus
- deploy a mail server with docker compose
- host my own email with spam filtering
- containerized mail server with ldap authentication
- set up postfix and dovecot without manual configuration

## When to choose
- you want a full mail stack (SMTP, IMAP, antispam, antivirus) in one container with file-based config
- you prefer simple, versioned configuration over a database-backed mail platform like Mailcow or Mailu
- you need LDAP integration or Kubernetes deployment for your mail infrastructure

## When to avoid
- you need a web-based admin UI for managing accounts and domains
- you want a groupware suite with calendar and contacts rather than just mail
- you cannot obtain proper DNS records (MX, SPF, DKIM, rDNS) or a clean IP for mail delivery
