You're right; I got them mixed up. My mistake. I had already seen Postmarks on HN when it was first posted, I guess. It looks like it was originally submitted two days ago and got put on HN's second chance shortlist, which makes it look like a new submission (shown as "8 hours ago" as of this writing, though the correct timestamp from 2023-09-05 doesn't get scrubbed).
