  • Local folders are traditionally meant for protocols like POP3, where the standard procedure for email is to get downloaded and deleted from the server. IMAP is designed to keep email on the server, like you’d expect in most cases.

    You can copy mail to local folders as a backup, but the problem you encountered is that the protocol was technically right, but you didn’t know about the details of migrating email providers. This problem should only happen in two scenarios: when your email vendor seriously fucks up, or when you migrate mail servers without first copying all the email over. As long as you keep backups for the first scenario, and remember to copy over email first during the next migration, you should be in the clear.

    You can use your email in whatever method you prefer, of course. I prefer to keep email centralised around my server. If you’re going local-first, you could consider using the older POP3 protocol instead, which is more local-oriented.



  • Tap on an app there. There are three settings. “disabled” for basically freezing apps once they’re no longer in the foreground, "enabled“ for doing things like occasionally checking for content updates j the background and playing music while other apps are on the forefront, and “unlimited” for the setting you’re thinking off, which badly designed apps often need to not be killed when they keep hitting the CPU in the background while the user hasn’t interacted with them for ages.

    Other manufacturers have even worse appp killers.


  • If you have your client configured for IMAP, Thunderbird will synchronise with the new server.

    If you did not transfer your emails from your old server to your new server, that means the new state is “empty inbox” and synchronising means “removing everything that’s available locally”.

    To fix this, either do a server-to-server transfer from the old email provider to the new one (there are tools to do that, like imapsync), or try importing emails from a backup into Thunderbird after synchronisation succeeds, so that Thunderbird will upload the messages. It’s possible that you will need to use a tool to rewrite the message IDs so that Thunderbird treats the messages as new items.

    If you have already cancelled your old server provider (so a server-to-server transfer is not possible), restoring from backups may be your only solution.

    If you don’t have any backups, your email may not be lost. The first thing you need to do is copy Thunderbird’s data folder to a backup location, just in case Thunderbird tries to do maintenance on the file while you’re performing recovery. Then, use a tool like Thunderbird Reset Status (I can’t quickly find a more up to date tool but they probably exist) to unmark the emails in the Thunderbird mail store as deleted. Then set up backups for your new mail server.

    If you use the trick above and Thunderbird starts deleting emails again, repeat the trick but break the email account settings first. Then, set up a second connection to your email account, drag over all the undeleted emails so they get uploaded to the new server.


  • MLS is designed to support that use case, but the spec to actually intercommunicate between services is still being developed by the MIMI group. MIMI is the logical but entirely optional extension of MLS.

    I don’t think carriers will want random chat apps to send messages for free to their infrastructure for spam prevention alone. Companies like Element and Wire are probably going all in on this, but Signal doesn’t even want you to use clients they didn’t compile, let alone federate between services.

    I believe WhatsApp has chosen to license its API in a documented fashion rather than implement a cross platform messaging protocol after they were forced to open up by the DMA. That said, there are a bunch of Facebook emails in the MIMI protocol discussions, so at least one of their messengers may still end up implementing MIMI when it’s finally finished.
