## :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.
##
