Web-based email list management system. GPL

Dada Mail 2.10.14 is an intuitive, Web-based email list management system, which runs on any hosting account that can execute custom CGI scripts. Dada Mail is also a conceptual art project. Dada Mail handles double opt-in/opt-out subscriptions, and can send complex announce-only and/or discussion mailing list messages. It also provides archiving, viewing, searching, resending, and syndicating (through RSS or Atom) sent messages. Dada Mail produces valid XHTML and sticks to best practices when creating email messages.
