Dada Mail is a web-based electronic mailing list management system that can be used for announcement lists. It can also be used to create and manage discussion lists, if you activate and configure an included plug-in called Dada Bridge, for which you will need to set a cron task.
Dada Mail handles Closed-Loop Opt-in subscriptions and Close-Loop Opt-out unsubscriptions, sending complex announce-only and/or discussion mailing list messages, archiving/viewing/searching/resending/syndicating (rss, atom) sent messages.
Unlike more traditional electronic mailing list software, like Majordomo (software) there is no email interface to send commands to Dada Mail. Rather, most all administration of the mailing list is done using a web-based control panel. Closed-Loop Opt-in subscriptions are done via sending a confirmation email message, but the actual mechanism is simply a unique confirmation URL.
Dada Mail was initially written in December 1999 and released as version 1.0 in January 2000, between Justin's first and second semester at the University of Colorado at Boulder. Its original name was Mojo Mail, a name that came to Justin after having a dream about making a successor to the program, Majordomo (software), after struggling with that program's email-based interface for a non-profit client.
Mr. Mojo Risin'
The name of this specific program was changed on December 1, 2003, after Justin Simoni received a letter from a lawyer representing Mediaplex Inc. that the name was in violation of their trademark. The name was changed to, Dada Mail. Dada is a direct reference to the early 20th century anti-art movement. Justin considers Dada Mail a conceptual work of art.
