What is OpenSMTPD

by z0ran

The great folks of OpenBSD have come out with yet another fabulous piece of software - OpenSMTPD. It's easier to safely configure than any other open source mail server. OpenSMTPD is a mail daemon currently developed by Gilles Chehade, Pierre-Yves Ritschard, Jacek Masiulaniec and others for the OpenBSD operating system. Its goal is to be a secure mailing daemon without the licensing restrictions of Postfix and without the added complexity of sendmail. It is stable, fast, secure, and easy to configure and use. OpenSMTPD is a FREE, easy to use implementation of the Simple Mail Transfer Protocol. It provides the ability to send and receive emails, as well as act as a relaying host. It aims to be as reliable as possible and to respect RFC and standard behaviors when they don't reduce the overall security of system.
