OpenSMTPD Description
OpenSMTPD serves as a free implementation of the SMTP protocol for server-side email communication, as laid out in RFC 5321, and incorporates several additional standard extensions. This software enables standard machines to facilitate email exchanges with other systems that also utilize the SMTP protocol. Born from a desire for a more satisfactory alternative to existing solutions, OpenSMTPD offers a comprehensive SMTP implementation. The project is mainly driven by developers Gilles Chehade and Eric Faurot, alongside contributions from numerous OpenBSD developers and collaborators from various other communities. Its development reflects a commitment to improving email server functionality and reliability across different platforms.

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.
