I assume by "nesting" you are referring to what I call "threading".

Are you talking about the threaded view in the Mailman archives of the
list, or the "conversation" view in your own gmail folders?

If gmail, see the FAQ at <http://wiki.list.org/x/2IA9> and see
<http://support.google.com/mail/bin/answer.py?hl=en&answer=5900> which
may be relevant.

If Mailman's archives, there are various possibilities. One scenario
is, e.g., you post, someone replies to you with Cc: to the list, you
reply to the reply you receive directly and timing is such that your
reply reaches the list before the first reply, your reply does not get
threaded as a child of the first reply because the first reply wasn't
there when your reply got threaded.

Another possibility is a reply get's sent to you and then resent to the
list as a separate message. If you reply to the copy sent to you, your
reply is not a reply to the message in the list archive so it isn't
threaded as such.

Also, some Debian/Ubuntu Mailman packages contained a bad patch that
caused messages with hyphens in their Message-Id: to be indented too
much in the threaded archive index. This was never an issue with the
source distribution, and the issue that the Debian patch was
addressing was fixed in the source distribution as of Mailman 2.1.13.
