Ponymail is an archive service for mailing lists. It is not a list provider.
Different mailing lists have different ways of managing subscriptions.
You need to contact the mailing list. In most cases the list headers will
show how to unsubscribe.
If you use the View Source button on any of the j-users mails, you should
see a line like:
List-Unsubscribe: <mailto:[email protected]>

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at [email protected] or file a JIRA ticket
with INFRA.
