Unfortunately, your mail client is one of those that stuffs up threading. There was no in-reply-to, nor a references header, in your email. Not only has it not inserted them, it's removed the references headers that were already there (written by the other replies). This makes it impossible for other clients to view your message in context with other messages. I expected better of gmail. Do you use gmail as a collection point, then write your replies with something else? Compliant mail clients *should* include those headers, perhaps even *must*, but it's been years since I've looked at mail RFCs (they're inserted when you reply). It doesn't matter whether *you* want threading in your client, or not. *That* is a choice for how you display your mail. The threading headers are for everyone else to be able to use. What happens when you break mail, in one way or another: Your replies are not seen with the messages that they're related to. They get missed, they get overlooked. It gets very hard to follow an ongoing thread when all the messages in that thread are scattered randomly amongst hundreds of other messages, especially when it's important to be able to follow the progress of something along the thread (and no, quoting the entire thread in each message is not the answer). Some helpers will give up helping after finding it a pain to follow an prolonged on-going conversation. Some will give up immediately. And if this converstion was on traditional usenet, rather than an email list, you'd be needing flameproof pants by now. ;-) -- [tim@localhost ~]$ uname -rsvp Linux 3.8.13-100.fc17.x86_64 #1 SMP Mon May 13 13:36:17 UTC 2013 x86_64 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists.
