Mailman is free software for managing electronic mail discussion and e-newsletter lists. We use Mailman because it supports built-in archiving, automatic bounce processing, content filtering, digest delivery and spam filters, and because it’s open-source.

What happens with your data
The system registers contact details (name, e-mail) for use in the administration of the subscription to lists and forums in Mailman. We will delete the contact details when the user terminates the subscription.
How to leave
The easiest way to unsubscribe from the mailing list is to send a message to firstname.lastname@example.org. Mailman will send you a confirmation message. If you reply to that message you will be unsubscribed. You do not need to know your password to do this.

What to do with people’s data
How we handle code of conduct violations
In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to make participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, education, socio-economic status, nationality, personal appearance, race, religion, or sexual identity and orientation.
By default, the full Foundation for Public Code code of conduct applies to all of our mailing lists. Some of the codebases in our stewardship have other codes of conduct, which will be linked from the description page of that mailing list.
Mailing list archives
Our intention is to keep all posts, unless someone specifically requests their data be removed. See our mailing lists archives. HyperKitty is the archiver project for the Mailman 3 suite, allowing users to browse mailing lists, start new threads and reply to existing threads, mark messages as favorite, search archives, and so on.
The Operations coordinator maintains Mailman and takes care of back end actions and user administration.
