## What it is
A simple and full-featured mail server distributed as a set of Docker images, bundling Postfix, Dovecot, Rspamd, ClamAV, Sieve, Fetchmail, webmail (Rainloop), Postfixadmin, DNS components, and automatic Let's Encrypt TLS. The project is explicitly marked unmaintained, with its last release in January 2020.

## Use cases
- self-host my own email server with docker
- run a private mail server with spam filtering and antivirus
- set up an smtp and imap server with dkim dmarc and spf
- host email for multiple domains on my own server
- dockerized postfix dovecot mailserver with let's encrypt certificates
- automatically gpg-encrypt outgoing email

## When to choose
- You need a complete batteries-included mail stack (SMTP, IMAP/POP3, webmail, anti-spam, antivirus, admin UI) deployed via Docker on your own server
- You want DKIM, DMARC, SPF, ARC, greylisting, and auto-renewed Let's Encrypt certificates configured out of the box
- You are studying the architecture or forking the codebase - it is the ancestor of the maintained docker-mailserver project

## When to avoid
- Any production deployment today - the project is explicitly unmaintained since 2020 and receives no security fixes
- You need current versions of Postfix, Dovecot, or Rspamd or timely vulnerability patches
- You want active community support - use a maintained successor such as docker-mailserver instead
