What I always intended with the tree walk is that you walk up the tree and if you find a DMARC record that isn't a PSD, that's your org domain. To see if two names are in relaxed alignment, do a tree walk for both and if they end at the same place, they're aligned. As a special case albeit a very common one, if one name is a descendant of the other, and there are no DMARC records in between, they're aligned.
Why would a DMARC record in between invalidate the alignment? DKIM-Signature: d=a.b.example.com [...] From: [email protected] _dmarc.example.com IN TXT "v=DMARC1; p=reject;" _dmarc.b.example.com. IN TXT "v=DMARC1; p=none; inbetween=y" Is that aligned? Best Ale -- _______________________________________________ dmarc mailing list [email protected] https://www.ietf.org/mailman/listinfo/dmarc
