:page_with_curl: About

A production-ready fullstack but simple containerized mail server (SMTP, IMAP, LDAP, Anti-spam, Anti-virus, etc.).

• Only configuration files, no SQL database. Keep it simple and versioned. Easy to deploy and upgrade.
• Originally created by @tomav, this project is now maintained by volunteers since January 2021.

> [!TIP]

Be sure to read [our documentation][documentation::web]. It provides guidance on initial setup of your mail server.

[!IMPORTANT]

If you have issues, please search through [the documentation][documentation::web] for your version before opening an issue.

The issue tracker is for issues, not for personal support.

Make sure the version of the documentation matches the image version you're using!
