Nothing that looks like mboxrd. I assume Right. The "x=m" requests an mbox; but it's only available via POST requests (to prevent search engine spiders from wasting time on non-HTML content). With the HTML output in a browser, the "mbox.gz" button makes the POST request and allows you to download the mbox. > this is stupid user error on my part, but even with that resolved, it > wouldn't have the nice git fetch properties of the git archive, i.e., > incremental updates of only new stuff, would it?

Small Maildirs work great, but large ones fall over. I don't think having a bunch of smaller Maildirs would help notmuch since notmuch still needs to know each file path. The only way I could see notmuch/Maildir working well is to keep the overall number of messages relatively small. One of my longer-term goals is to write a mairix-like tool in Perl which works with public-inbox archives; but I barely have enough time for public-inbox these days :< mairix works with gzipped mboxes, which is great for large archives; but the indexing falls over since it rewrites the entire search index every time. SSDs have died as a result :< > But I feel like I must be missing the solution that's obvious to > everybody but me. Nope, you're not alone :) There's not a lot of mail software which can handle LKML-sized histories efficiently. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
