Can lists.preview.boost.org be configured to provide per-date and per-author views like the old archive page?
By the way, all list owners and settings are imported. The configuration remains as similar as possible. However, there are limits. mm2 offers the choice of "by date" or "by thread" display. It looks like Hyperkitty defaults to a "Threads" view, where replies are included below the top-level one. That is the way mm3 works. There isn't a "by date" view (separate from a threads view).
Can these be fixed, or do the source files for those messages not contain the original data?
Consider this page that garbles grisumbras's name: https://listarchives.boost.org/boost-announce/2025/05/date.php The most "original content" available on wowbagger are the archive files. They contain something illegible: "Ð ” Ð ¼ Ð " Those characters are copied exactly verbatim to the listarchives machine, and it shows the same bad result as before. But the machine https://listarchives.boost.org shouldn't be a major focus. It's a sort of backup. The new real server will also have the imports, corrected/fixed, and they are searchable.
