@movq I figured it will be something like this, yet, you were able to reply just fine, and I wasn't. Looking at your twtxt.txt I see this line:
2024-09-16T17:37:14+00:00\t(#o6dsrga) @<prologic https://twtxt.net/user/prologic/twtxt.txt>
@<quark https://ferengi.one/twtxt.txt> This is what I get. 🤔
Which is using the right hash. Mine, on the other hand, when I replied to the original, old style message (Message-Id: <o6dsrga>), looks like this:
2024-09-16T16:42:27+00:00\t(#o) @<prologic https://twtxt.net/user/prologic/twtxt.txt> this was your first twtxt. Cool! :-P
What did you do to make yours work? I simply went to the oldest @prologic's entry on my Maildir, and replied to it (jenny set the reply-to hash to #o, even though the Message-Id is o6dsrga). Since jenny can't fetch archived twtxts, how could I go to re-fetch everything? And, most importantly, would re-fetching fix the Message-Id:?
