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.
