It appears that Scott Kitterman <sklist@kitterman.com> said: >As written, I think it produces the correct result. I now think it's close but not quite. >As written you take the domain with a (non-PSD) DMARC record with the fewest >labels, .... How about this? a NXDOMAIN (or psd=y, doesn't matter) b.a blah c.b.a psd=y d.c.b.a blah e.d.c.b.a NXDOMAIN The org or policy domain for e.d.c.b.a is d.c.b.a, but the one with the fewest labels is b.a. This is why we walk up rather than down. This shouldn't be hard to fix but I'm trying to figure out the least confusing way of saying it. R's, John
