I'm looking for a way to have group discussions using email and without centralized storage.
I want to use email, because all members already have it. They need no new software or new accounts.
@neauoire I have yet to find a mailing list service that doesn't centrally store the emails. There don't seem to be a lot of email group discussion providers around any more - the majority switched to WhatsApp & Co. :/
@rostiger you can make one up, if you just want to redirect emails between friends, you can send up a mail server with an address that will only forward an email to a list of recipients, if you don't want it to be centralized, you could write a setup guide and get everyone in the list to spin their own.
@rostiger @neauoire and it really depends on your security posture here. Will all the emails be GPG encrypted? If not all the emails will be stored as plaintext once per recipient in their mail servers. Storing it once more on a central mailserver is not concern in this case. If you want to avoid long term storage you can set an expiration or cron job to delete them after N days. Cannot achieve anonymous & secure communication via email unfortunately.
@peregrine That's a good point to consider, thanks! Since most people in the group aren't tech-savvy, they are using unencrypted, "free" services (mostly gmail & co). Nothing that is written in the group can ever be secure or anonymous. From that perspective, central storage isn't an issue anymore.
