Review of draft-ietf-emailcore-as-28

I am the designated DNS Directorate reviewer for draft-ietf-emailcore-as-28. The draft is on standards track and makes recommendations for the use of features of the email core protocols.

DNS is only mentioned on a few places in the draft, mainly in sections 2.1 (DNS for name resolution) and 6.1.3. (which refers to the use of DNSSEC/DANE). Both sections refer to the use of DNS but do not change/extend/… DNS itself, therefor there is not much to review which is related to DNS. The comment from the dnsdir review of version -26 was addressed.

Overall, I think the draft is ready for publication.
