There are all sorts of reasons for publishing ADSP=discarable, from
"the
domain isn't used to send email" (analagous to "spf -all")
Quite right, in which case I hope you'll agree that throwing mail away
is
exactly the right thing to do.
to "our domain is widely spoofed (because of its sensitive nature),
and
we absolutely do sign all our email".
That would be dkim=all, not dkim=discardable.
As I keep saying over and over, discardable really means discardable:
if
in doubt, throw it away. It does NOT, repeat NOT, mean high value
mail.
It means low value mail.
-1
It does not mean low value mail and I don't think you will find a
sending mplementing dkim=discardable that would agree with you. In the
case of the domain actually sending mail, what is being said is that the
risk of phishing/badness/abuse is great enough that when in doubt,
discard it if it fails to validate or does not have a signature. This is
significantly different than "it means low value mail".
