How to keep all email locally in a useful format that can be searched across devices? - eviltoast

I have an account on an SMTP server. The server has a storage quota. I’d like the delete stuff from the server but keep it locally in case I need it. Just in case.

I’d like to be able to access the mail somehow on other computers and hopefully mobile devices on my network so that it can be searched when needed. I’m not sure what the best interface for that would be. A webmail client?

One option would be to use Thunderbird or another client to download the mail once in a while but disable deleting local messages when they are removed from the server. Would Thunderbird store the messages in a format I can use readily with other applications? Or should I use something else to download the mail?

What about situations where messages are moved from one folder to another on the server? Would I get a duplicate locally of the message appearing in both locations? Not sure how the storage and metadata actually are.

Also, is it possible in such a situation to put a message back on the server if I realize it was deleted in error?

Any idea would be welcome. I am a bit stuck.

I can use the command line comfortably but ideally I’d have a solution that doesn’t rely on the terminal to find find messages and such. I don’t really like terminal mail clients.

    Well, I’ve solved it! I now have a web interface (accessible via VPN, although, in principle, I could expose it to the internet) that allows fast, full-text search of all my old emails. Here is the recipe:

    1. Maildir: I converted all my mbox files to maildir using this python script: https://superuser.com/questions/1169371/how-to-convert-mbox-mail-files-as-found-in-thunderbird-dir-to-maildir#1343019
    2. Installed notmuch via my distro’s repository and set it up (notmuch setup & notmuch new). This creates a new folder in your maildir directory containing full-text search info.
    3. Installed netviel via python3 -m pip install netviel and then ran it via python3 -m netviel

    That’s it! This let’s you search locally. I actually did a few more steps because I wanted to containerize this thing so I could run it on my NAS. I’d be happy to go into detail about that too, if you’re interested. One hiccup was that, for some reason, netviel binds to 127.0.0.1 instead of 0.0.0.0, and there is no way to change that without compiling the project yourself. But, I found a workaround for my Docker container where you can use socat bound to 0.0.0.0 to redirect requests to netviel, so that requests from other computers appear local to netviel.

    Anyway, that makes it all sound more complicated than it is. I am super-pleased to have solved this problem at last!
