 Hi,

 I use buildbot 0.8.10 to report build failures via email to a number of
 people. The amount of emails generated for every commit on the repository
 can be quite big if there are many builders around. It would be nice to
 have these emails be on the same thread instead of arriving as individual
 emails on people's inboxes. That would help group related emails together
 when the repository is busy and lots of different builds are started for
 new commits.
 I understand that the buildSetSummary=True can help with that a bit, but
 for a number of reasons it is not convenient for our needs.
