4.1.4 Internationalized mail In internationalized messages (RFC 6532) many header fields can contain UTF-8 as well as ASCII text. The changes for EAI are all inherited from DKIM as updated by [draft-levine-eaiauth] and Authentication-Restukts as updated in [rfc7601bis], but are called out here for emphasis. in an AS header, the d= s= tags can be contain U-labels. In an AMS header, the d= s= tags can contain U-labels, i= can have UTF-8 in the local-part and U-labels in the domain, and in all tags, non-ASCII characters need not be quoted in dkim-quoted-printable. The AAR header allows UTF-8 in the same places that A-R does, as described in [7601bis]. _______________________________________________ dmarc mailing list [email protected] https://www.ietf.org/mailman/listinfo/dmarc
