quite the opposite is true, that's what delegations are for. I'd agree it's not a threat - but a misconception. Hierarchy in naming does neither imply nor follow hierarchy in administration (or administrative control). Any attempt to set 'domain wide' defaults or values misses that fact. It's related to "DNS tree climbing" or lessons (not) learned from RFC 1535. -Peter _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html
