I would chop a lot of that out. If people don't already know how DNS names work, they're not going to be able to use DMARC. >My thought is to add text based on the above mail to the paragraph: > >PSDs are important to DMARC because subdomains of a PSD are different >organizations and subdomains of non-PSDs are part of the same organization. That seems OK. R's, John _______________________________________________ dmarc mailing list dmarc@ietf.org https://www.ietf.org/mailman/listinfo/dmarc
