Hello

I was playing around with some experimental code and I noticed
that 'open.nlnetlabs.nl' does not set the DO bit in the reply, when
it is set in the query, as is required per RFC 3225.

NSD:

% dig @open.nlnetlabs.nl +dnssec mx miek.nl | grep EDNS
; EDNS: version: 0, flags:; udp: 4096

BIND:

% dig @miek.nl +dnssec mx miek.nl | grep EDNS
; EDNS: version: 0, flags: do; udp: 4096

 grtz,
