GNU Mailman is a computer software application from the GNU Project for managing electronic mailing lists.[4][5] Mailman is coded primarily in Python and currently maintained by Barry Warsaw. Mailman is free software, licensed under the GNU General Public License.[5]


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.[6] Ken Manheimer at CNRI, who was looking for a replacement for Majordomo, then took over development. When Manheimer left CNRI, Barry Warsaw took over. Mailman 3, the first major new version in over a decade was released in April 2015.[7]
