Delete mails and "reading notifications" from server after x days/weeks/or month #84

Delete mails and reading notifications from server after x days/weeks/or month

Currently my mailbox space is wasted by "one line mails and reading notifications". So there should be a option to delete older messages and reading notification mails automatically after a special time.

I know the Delta Chat guys have started this in there core repository. But it seems they are a little bit fearful to delete wrong mails ;-)

Maybe you could this push a little bit. I think it's really important to save space in the mailbox.

What do you think?

Definitive worth investigating, thanks for your input. I think keeping the inbox clean is really important, on the other hand is the passive way of dealing with "deleting users mail" always a good one, because if something wrong is deleted and data loss is produced probably a whole app / product is screwed. I will put this on the table for the next internal discussion and will also think about talking to the DCC team in regards to this topic, as I really like the idea (especially for deleting reading notifications, as those doesn't contain any useful information after the initial use).

I really like the idea of server flags suggested in deltachat-core issue #112. If the server supports custom flags, we could delete receipt notifications and set the flag instead. Maybe even push for a new standard IMAP flag.

Note: With IMAP, it's not possible to modify headers of an existing mail without deleting and re-creating it with a new ID. Which would cause other clients to re-download it.

Another idea might me to archive old messages instead of deleting them. The space savings could be achieved by collecting them in a single mail and compressing it before re-encrypting.

Maybe to be more sure you could older messages move to the waste bin instead delete it directly. Or something.

This folder is normally under control of the user.

@webratte I just put this topic up again in one of our meetings and it's definitely something we plan to integrate in a way. But for now we are unsure if this will be in the client or if there will be even some suggestions in the COI specs (https://github.com/coi-dev/coi-specs/blob/master/coi-client-spec.md). For the MVP of this app it's probably out of scope, but the benefits are there, so we will probably try to integrate something like this in the app / the standard at a later point. If a more detailed plan is available I will update this issue. Thanks again for your input :+1:
