GNU Mailman is a computer software application from the GNU Project for managing electronic mailing lists. Mailman is coded primarily in Python and currently maintained by Barry Warsaw. Mailman is free software, distributed under the GNU General Public License.
A very early version of Mailman was written by John Viega while a graduate student, who then lost his copy of the source in a hard drive crash sometime around 1998. Ken Manheimer at CNRI, who was looking for a replacement for Majordomo, then took over development. When Manheimer left CNRI, Barry Warsaw took over. Version 3 has been under development since 2009, with second and third betas released in 2012.
