I should clarify the above. In all cases I collected three counts:

a) mail with VALID signatures (either direct or through a mailing list,
as long as a ML didn't invalidate a signature);

b) mail with FAILED signatures coming through a mailing list, i.e. carrying
header fields like List-Id, List-Post, Mailing-List, or with an
envelope address like *-(request|bounces|admin|owner) or owner-* ;

c) remaining mail with FAILED signatures.

Only mail with signatures (valid or invalid) were considered.
Unsigned mail even if claiming to be from given domains was not counted.

So the percentages I gave are a/(a+b+c), b/(a+b+c) and c/(a+b+c).
