That's an interesting number, higher than I'd have thought. I'd
have guessed ~50%.
- any idea why its so high (are you doing anything odd in the
signatures?)
l= with some z= magic. the point being that we understand the risks, and
we don't want net.busybodies telling us what is best for us. If any of this
becomes a real life problem -- which it is not -- there are plenty of other
mitigations we can take.
- what causes contribute to the 0.4%
there are definitely mailing lists out there that do things that we can't
recover from -- yahoogroups as an example. More interestingly though,
there are mailing lists managers that actually mangle the DKIM-signature
itself under some circumstances -- would that we kept nowsp for the
headers. Then the rest fall into a grab bag of different reasons.
