Exim: a case study in sustainability, 6 Dec 2012 [cached]
by Philip Hazel, University of Cambridge Computing Service on 5 June 2007 , last updated
This case study, examining the Exim project, has been written by Philip Hazel, University of Cambridge Computing Service.
Philip Hazel retired from the University of Cambridge in September 2007, having headed up the development of Exim throughout its history. In the run up to his retirement a number of changes were made to the way the project works, with a publicly visible (with a small number of committers) CVS archive of source and documentation made available on a University of Cambridge system as well as a publicly visible bug tracking system. Exim releases after 4.50 (Early 2005) had a number of changes committed directly by various authors (around 6 people in total) into CVS, although the majority of changes were still committed by Philip.
There has been one release (version 4.69) since Philip retired, although there are a significant number of bug fixes or enhancements currently within the source repository.
Philip Hazel has now retired, see the current status section for more information. ↩
