That is more accurate Scott. Also I removed an extra sentence on comma-separated.
Updated https://gist.github.com/moonshiner/70377e69d482e7bf3a927d5ac468babb 5.3. General Record Format auth: (comma-separated plain-text list of dmarc-methods; OPTIONAL; default is "spf,dkim") Indicates the supported authentication methods. The order of the list is not significant and unknown methods are ignored. Possible values are as follows: dkim: Authenticate with DKIM spf: Authenticate with SPF An empty list indicates the tag is ignored. If any listed method passes and is aligned, then DMARC passes. 5.4. Formal Definition dmarc-method = "dkim" / "spf" dmarc-auth = "auth" equals dmarc-method *(*WSP "," *WSP dmarc-method) I did not word smith Wei's 4.3 text.
