There's always been demand for a way to download a list archive as an mbox file

This is a feature I am interested in pursuing. From a very (very) high level, the process of creating an mbox file out a list archive should entail:

1. Determine which messages to include in the mbox. An entire list archive is clearly one choice, but is there also interest in generating mbox files for specific threads, list archieves between specific dates, etc.?
2. For each message, append plaintext to mbox file. Is this the part where we risk "blocking the UI"? Certainly for hundreds of thousands of messages, this will be a computationally intensive step, so will this have to be run in a separate thread?
3. Present mbox file to user for download. I'm hoping this is a trivial step, but I'm not sure about some of the specifics. For example, is Hyperkitty only able to run on apache, or is the choice of web server entirely up to the web admin? How we ultimately serve the file will depend on these details.

Aurélien, just because I'm new to the codebase, what are the challenges you see in implementing this feature? Whatever details you can give me will help me set my milestones.

Thanks, David

I'm interested in contributing to the Hyperkitty archiver. Specifically, it looks like some requested features for Hyperkitty include rss syndication for entire mailing lists/specific users/specific threads, and the ability to view entire threads as plaintext and download that plaintext.

We don't have either feature yet, but I think RSS syndication would be much too short for a GSOC project. There's always been demand for a way to download a list archive as an mbox file, and it's reasonably complicated if you want to avoid blocking the UI, so this may be a good project similar to the plaintext threads feature you mention.
