That is, the Newsgroups header shows one newsgroup (uk.tech.broadcast) that I never visited, but is missing the a.c.s.thunderbird newsgroup that I do visit and where I saw the article. Newsgroups: uk.tech.broadcast ^___ alt.comp.software.thunderbird is not specified I thought maybe the poster got his client to falsify the Newsgroups header since the client creates that header in the message. What was specified in the Newsgroups header within the message might not match the GROUP and POST commands the client sent to the NNTP server. Turns out Dialog might have a bug. I used the following command after telnetting into and authenticating to my NNTP server (news.individual.net): newnews alt.comp.software.thunderbird 20210425 000000 The poster had submitted that day, so I listed all new articles in the a.c.s.thunderbird newsgroup for that day. It isn't a busy newsgroup, so there weren't that many message IDs to list. I pasted the message IDs list into Notepad and searched on <firstname.lastname@example.org> which is the MID for the poster "MB". Wasn't found. Despite Dialog showing the poster's article in the a.c.s.thunderbird newsgroup on the NIN server, the server says there is no such article in that group. - On news.individual.net (NIN) server - in the alt.comp.software.thunderbird newsgroup - Dialog shows a message from MB (<email@example.com>) titled "Thunderbird - disabling display of quoted text" - Yet the server says there is no such MID in that newsgroup The poster, MB, submitted to the uk.tech.broadcast newsgroup, and only to that newsgroup, but Dialog shows MB's message in a.c.s.thunderbird. In other words, Dialog is showing an article in the wrong newsgroup. Another user, Andy Burns, replied to MB's post in uk.tech.broadcast, but Andy added a.c.s.thunderbird to his reply. MB posted to uk.tech.broadcast, but Andy cross-posted his reply to both uk.tech.broadcast and a.c.s.thunderbird. I would've expected Dialog to show a new thread in a.c.s.thunderbird starting with Andy's post, and MB's post would be missing in that newsgroup. Besides changing his Newsgroups header to include both newsgroups, Andy's References header points back to MB's MID for his message. Still, I would not expect Dialog to yank over an article from another newsgroup to show the thread tree starting with MB's post. In a.c.s.thunderbird, the thread should've started with Andy's post. At first I thought MB must have somehow gotten his client to lie to where it submitted. His client showed 1 newsgroup in the Newsgroups header, but his client could've issued multiple pairs of GROUP and POST commands to submit to 2 newsgroups. Nope, the NIN server that I use said there was no MB post in the a.c.s.thunderbird newsgroup, so Dialog was wrong to show it there. Andy changed Newsgroups in his reply to include the original newsgroup and to add a.c.s.thunderbird (to present MB's post to the appropriate newsgroup). Andy's reply has a References header pointing back to MB's post in the uk.tech.broadcast newsgroup. However, neither of those should have gotten Dialog to present MB's post as being in the a.c.s.thunderbird newsgroup. Does Dialog have a "feature" that it completes a thread tree back to its parent even when the article is in a different newsgroup when the parent is on the same NNTP server?
