Every message has a unique message ID, so if you have a look at the source of your message, you will find a header which says Message-ID: <3FDAF73A.2080804@xxxxxxxxxxxxxx> When replying to individual messages, the mail client adds a header In-Reply-To which quotes that message ID. Have a look at the headers for this message, and you'll see this header with the message-ID above. This way mail clients know how to do the threading. Some mail software tries to be clever and work with the subject lines and attempt to decide if it is a reply, but in essence threading depends upon the In-Reply-To field. > The reason I ask is that I get the MIME digest and if all that is > required to maintain a thread is the subject line--no problem but If > there is some kind of non-subject line tracking involved, how do I > reply from a digest.? How you can reply from such a MIME digest and maintain threading, I'm afraid I don't know.
