The archiving is done by a different software than the mailinglist
handling. So not sure whether there is a way to guarantee consistency
even if we tried.

That was one of the reasons to add the mail-archive.com headers -
although they are not available instantly, but only after the cronjobs
at mail-archive.com are run, so there's always a little delay until
those work.

It would take considerable amount of work to align them, and unless it
is really a one-time discrepancy (not sure about that, maybe the list
also counts received but not-moderated-through messages and hence will
get out of sync again once someone doesn't let spam pass.

Well - no idea - would be a volunteer's task to first check what
numbers are missing from the index/whether the index commands return
each and every message or whether there are skips already.

Maybe for one or two lists, but not for the ones that were created
later on like design (at least I don't know a reason why there should
be 8 "test" or whatever messages that would then have been removed)

Referring to mails by ID like that is very fragile, better use msg-id
or a hash like from mail-archive.com, that way you can restore them.

When you only rely on arbitrary web-archive numbers/urls, like OOo
did, you end up with non-working links once the archive is moved to
another engine/infrastructure,...

(mail-archive.com hashes/links are urlsafe bencoded  sha1sums of
msg-id & list-address)

So when there are "skip" in the lists's own index, then there is no
way at all to keep them in sync. When they are continuous without
exception, then it is a question of what messages are missing from the
archive.

(But I won't do this comparison myself for sure :-)
