Modoboa
Take back your autonomy and safeguard your personal information by setting up your own email server, a process that can be completed in under 10 minutes!
With Modoboa, you can establish your email server at no cost in less than 10 minutes. When it comes to establishing a mailbox, you typically have a few choices:
- Rely on services provided by internet and infrastructure companies (like Orange, Vodafone, OVH, or Gandi), which often require a monthly or annual fee, but they come with limitations on customization, configuration options, and the number of domains and mailboxes you can use.
- Opt for free email services (such as Gmail, Live, or Yahoo), which come with restrictions and often exploit your data for commercial gain.
- Set up your own email server, although this usually demands a significant level of technical expertise for proper installation and configuration.
Modoboa presents a viable alternative to these three options. It liberates you from the constraints of traditional email providers, allowing anyone to create a secure email server independently. Best of all, this entire process takes less than 10 minutes and is completely free of charge. Embrace the freedom of managing your own email with ease!

Courier
The Courier mail transfer agent (MTA) serves as a comprehensive mail and groupware server that utilizes widely recognized protocols, including ESMTP, IMAP, POP3, LDAP, SSL, and HTTP. Within a unified framework, Courier delivers a range of services, such as ESMTP, IMAP, POP3, webmail, and mailing list functionalities, allowing users to easily enable or disable specific components as needed. Recently, the Courier mail server has introduced fundamental web-based calendaring and scheduling features within its webmail module, with plans for more sophisticated groupware calendaring capabilities to come shortly. Notably, the source code for the Courier mail server is designed to compile on most POSIX-compliant operating systems that utilize Linux or BSD-derived kernels, and it can also be successfully compiled on Solaris and AIX systems, provided users utilize the appropriate freeware add-on tools from Sun or IBM. The development of the Courier mail server is rooted in a combination of several interrelated projects that converged into its current form, and it also incorporates SMTP extensions specifically aimed at enhancing mailing list management functionality. In this way, Courier not only serves as a versatile mail server but also as a collaborative tool for users seeking effective communication solutions.
