OpenSMTPD is primarily developed by Gilles Chehade, Eric Faurot and Charles Longeau as part of the OpenBSD project. Its design goals include security, reliability, ease of configuration, and support for common use cases. The source code is available under the ISC license.
Its portable version, like that of OpenSSH, is developed as a child project which adds the portability code to the OpenBSD version and releases it separately. The portable version was initiated by Charles Longeau and adds support for multiple operating systems including NetBSD, FreeBSD, DragonFly BSD, and several Linux distributions.
