Broadcast message from server admin to all users?

[Dio]

Hi,

I’ve just set up a chatmail server for testing. First thing, that comes to my mind now: Is it possible to send a broadcast message to all users on the server?
E.g.: “Server will be down for mainteance in the next 2 hours” or even “Server will be shutdown forever, please migrate your stuff!”

Thanks

Workarounds:

• ICS
• RSS
• DC broadcast channels (beta)
• allow unencrypted reception (from the operator at least) and then send them a message about it
• the chatmail homepage itself - the operator may disable IMAP for a day every week (or stop receiving new messages other than by the operator) and then most users would probably visit the webpage to see what’s happening
• return IMAP/SMTP errors for some things, but most users won’t be able to find them (in the log or in the message info window)
• Fediverse or any other contact form published on the web page

Reliable way for server admin to communicate with his users

Server admin often needs a way to communicate to it’s users, to inform them on server downtimes, policy changs, service termination, etc. AFAIK in case of DC it’s not possible right now. Admin of public chatmail server usually don’t know it’s clients personally, and can’t write to them, despite he has a list of their email addresses. Broadcast messages may be a solution, if all server users will be subscribed right after login creation. But I don’t know if it will be possible at all. Public …

Announcement channels for chatmail

Sometimes server maintainers might like to make announcements to notify users for things like planned maintenance, scheduled downtime, data breaches, etc. Has it been considered giving chatmail server maintainers an easy way to make announcements? Simply mailing every account on the server is one option, but maybe it would be better if Delta Chat checks if an “announcements” file exists on the server and displays the announcements with a nice UI in the app?
