Sendmail is an open source mail transfer agent (MTA) used for routing and delivery e-mail. The original version of Sendmail was written by Eric Allman in the early 1980s. It is estimated that Sendmail is installed on 60 to 80 percent of the Internet’s mail-server computers.
Apache Web server
Often referred to as simply Apache, a public-domain open source Web server developed by a loosely knit group of programmers. The first version of Apache, based on the NCSA httpd Web server, was developed in 1995. Core development of the Apache Web server is performed by a group of about 20 volunteer programmers, called the Apache Group. However, because the source code is freely available, anyone can adapt the server for specific needs, and there is a large public library of Apache add-ons.

The Open Source Definition was written by Bruce Perens as “The Debian Free Software Guidelines”, and refined it using the comments of the Debian developers in a month-long e-mail conference in June, 1997. He removed the Debian-specific references from the document to create the “Open Source Definition.”
