Poste.io

All-in-one mail server in a single container

About Poste.io

Poste.io is a mail server package that bundles SMTP, IMAP, webmail, and antispam into one easy-to-deploy container image. You can deploy it with common tooling such as Docker or a standard package install and integrate it with the systems you already run. That makes it a practical fit for homelab users, small teams, and organizations that value privacy, ownership, and predictable costs over time.
