For example, in:
There are a lot of automated messages from Bugzilla. Any given bug tends to have plenty of these messages; the individual messages all show up as separate discussion topics in Nabble.
There ought to be a way to have messages about the same bug be automatically combined into the same thread by Nabble. Currently, someone viewing the Nabble page has to scan through page after page of bugmails to find only a few separate discussion topics (both the bugmails, and topics sent directly to the mailing list).
I looked in the Bugzilla bugtracker (bugzilla.mozilla.org) for activity about this, and it seems that threadable e-mails are considered a supported feature of Bugzilla.
This is the same for the dev@ list. I've search if I can do something on the Nabble side but didn't find anything. So I think this should be a bugzilla setting - Sophie
