True, I'm guilty as charged. ;)

Somehow, I always presume that list owner must be on the list, but of
course it's not always true. Not even common these days.

While I don't see that header yet (for example in your message), of
course it's everything I asked for. There's nothing special in Sender:
header. Actually, you can use whatever header you want, it's just my
opinion that one such header MUST exist. Otherwise it's hard and error
prone to split mailing lists. I don't like spliting emails on headers
that are not primarily for that purpose (To, From, Received,
Subject...). It's asking for trouble.

For example, my split rules are full of different headers for
different mailing lists, I don't care, all of them work well, it's
just that ding list lost the last such header without warning and
mails started mixing with private/business mail. Thankfully this list
is not high traffic, so it wasn't such a big problem, but when that
happens to high volume lists like linux-kernel and you're on a 2 day
vacation... you know what happens. ;)

Example headers from my nnmail-split-fancy:

x-beenthere (mailman lists)
x-mailing-list
sender

Thank you!
