mail in a box

We have hosted the application mail in a box in order to run this application in our online workstations with Wine or directly.

Quick description about mail in a box:

Mail-in-a-Box helps individuals take back control of their email by defining a one-click, easy-to-deploy SMTP+everything else server, a mail server in a box. Mail-in-a-Box lets you become your own mail service provider in a few easy steps. It�s sort of like making your own gmail, but one you control from top to bottom. Technically, Mail-in-a-Box turns a fresh cloud computer into a working mail server. But you don�t need to be a technology expert to set it up. Our goals are to make deploying a good mail server easy, promote decentralization, innovation, and privacy on the web, have automated, auditable, and idempotent configuration, not make a totally unhackable, NSA-proof server, and not make something customizable by power users. Mail-in-a-Box turns a fresh Ubuntu 18.04 LTS 64-bit machine into a working mail server by installing and configuring various components. It is a one-click email appliance. There are no user-configurable setup options. It "just works.".

Features:

• Spam filtering (spamassassin) and greylisting (postgrey)
• TLS certificates are automatically provisioned using Let's Encrypt for protecting https and all of the other services on the box
• Backups (duplicity), firewall (ufw), intrusion protection (fail2ban), and basic system monitoring (munin)
• Webmail (Roundcube), mail filter rules, and email client autoconfig settings (served by nginx)
• SMTP (postfix), IMAP (Dovecot), CardDAV/CalDAV (Nextcloud), and Exchange ActiveSync (z-push) servers
• Comprehensive health monitoring that checks each day that services are running, ports are open, TLS certificates are valid, and DNS records are correct
• A control panel for adding/removing mail users, aliases, custom DNS records, configuring backups, etc.

Programming Language: Python.
