What can one find continuing the walk after psd=y?
I have looked at every domain in the PSL that publishes a DMARC record and
other than the three that are in Scott's PSD list, what I found was totally
random. Some looked reasonable, some looked broken. In practice I think the
details are unlikely to matter because if they send mail at all, the SPF and
DKIM identities are going to be the same as the From so they'll be aligned no
matter what rule we use.
Indeed, in realistic cases walking the tree beyond psd=y results in just a
useless query. I have shown an unrealistic case where not stopping at psd=y
results in a wrong determination.
Would you please show an example, realistic or not, where not stopping for
psd=y in step 2 leads to a useful result?
Best
Ale
