That's an ingenious idea. I tried it with Evolution and indeed it works, so Evo at least *does* appear to take note of the References header. All the same, when I delete the common parent of two messages (which were previously at the same hierarchical level) then one appears as the parent of the other, even when I turn off the "fall back on Subject threading" option, so the conclusion is not completely iron-clad, i.e. Evo seems to be doing something else (I checked carefully that neither message had the Message-ID of the other anywhere in its headers.) Or it could just be an Evo bug. poc -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
