The GNOME mailing lists are kindly hosted by Red Hat and using Mailman.
List of all public mailing lists: https://mail.gnome.org/mailman/listinfo
For obsolete list removal, see /MailingListRemoval.
For renaming a list see NewListRequest#Renaming_lists.
For information on subscription management, see /SubscriptionManagement.
We use 'mhonarc' for the list archives, as it's a whole load better than the standard mailman archiving.
Previously, we used 'Namazu' for searching the list archives. Instead of Namazu we now rely on Google. As a result, private archives cannot be searched.
