Kinda OT. But interested what's the difference between reply-list and to.
In addition, based on what information a thread is formed?
Each email program uses different buttons and/or menu items to enable
the user. So I'm using button names from Thunderbird, but most email
programs should have equivalent.
WHen I use "Write", a new message is composed, and I get to fill in the
subject line, the to: field, etc. Such a message always starts a new
thread.
When I use Reply-list, there is a field within the header of the new
message that refers to the previous one. That's in addition to the
automatic filling in of the subj: line with a "Re:", any quoting that
may occur, etc. I also could use Reply-All, and trim out the private
recipients. But reply-list is easier, and more likely to end up correct.
There is a LOT of information in those headers, and I'm not sure just
which one is filled in to make threading work. I'm assuming it's the
"References:" field. If you want to see the headers (and the
body/bodies), you can use (in Thunderbird) the
View->Message Source
menu item.
For example in the message you just sent, there are 104 lines before it
gets to the first par of your actual message body. That's almost 6k of
stuff.
Anyway, when I display the messages, they're shown in a hierarchical
tree. It's hard to imagine reading a newsgroup like this without that,
although I did in the early 80's, under MSDOS. I wrote a utility which
sorted the messages by subject line, and at least I tended to see
related messages together (except that already-read messages were only
visible by search, and if somebody changed the subject line, the thread
was (for me only) broken.
