Bummer. Yet another thing to not like about gmail ...

(Above subsequently noted to not be completely correct)
Threading in Mailman's pipermail archive was designed to identify the
parent of the current message as follows:
1) If the current message has an In-Reply-To: header, the parent is the
message in the archive with Message-ID: = this message's In-Reply-To:,
or if no such message exists, this message has no parent.
2) If the current message still has no parent, but it has a References:
header, and one or more of the IDs in the References: header is = the
Message-ID of a message in the archive, the parent of this message is
the newest referenced message. If none of the referenced messages are
in the archive, this message has no parent.
3) If the current message still has no parent, it's parent is the
oldest message in the archive with a matching subject, if any.
In the above, "in the archive" really means in the archive for the
current month or whatever the archive frequency is. Also, step 3),
threading by subject, was broken prior to Mailman 2.1.14 and may still
not be completely fixed. See
