Subject: future date in Date header pinning thread to top of $inbox/
Date: Sat, 04 Feb 2023 12:25:40 -0500

As noted by Ihor on the Org list (<87pmarnhlr.fsf@localhost>), Org's
public-inbox archive has a thread pinned to the top of the $inbox/
overview:

 * https://yhetil.org/orgmode/

That thread has a message where a sender set his Date to a future date:

  $ curl -fSsL https://yhetil.org/orgmode/ZT2vNKsf3Lp5xit3@protected.localdomain/raw | \
    grep Date:
  Date: Sun, 29 Oct 2023 04:02:44 +0300

Based on grepping around the public-inbox tree and Git history, I know
that there are spots in public-inbox that prefer a date from the
Received headers over the one from the Date header.  Would that make
sense to do here too to reduce the chances of a date from the future
pinning a thread?  (Or perhaps that's already the intention and
something's off here?)

Thanks.
