Description

Mail-in-a-Box transforms a fresh Ubuntu server into a fully functioning mail server with a single command. It automatically installs and configures Postfix, Dovecot, Roundcube webmail, Nextcloud, a DNS server, and automatic TLS certificates. The solution is aimed at technically proficient users who want to run their own mail server without having to set up each component individually. A clear status page helps with diagnostics.
