# Mailing Lists
The CentOS Project hosts some public mailing lists that people can subscribe to.
It's hosted at [https://lists.centos.org](https://lists.centos.org).
Some links:
* [Upstream mailman 3](https://docs.mailman3.org/en/latest/) documentation
* [mailman3](https://github.com/centos/ansible-role-mailman3) ansible role
## Authentication
It's just relying on OpenIDC for authentication, as other services in centos infra, and so using https://id.centos.org as IdP (enrolled into Fedora IPA)
