Poking around a little on the pipermail discussion lists, it
looks like pipermail (a script in the mailman package) uses
three things to determine whether a message is in a thread:
(1) In-Reply-To header
(2) References header
(3) same subject
Your mail had none of those things, so I don't know why it was
shown as a reply.
I see other examples in the archives of mis-threading. One
example is below:
To really see what's going on, you have to look at the source of
the original message (I used Thunderbird). All of the headers
looked "normal" to me.
I think this is a bug in pipermail, and has nothing to do with
the configuration of your web mail.
