DMARC behaviour is unclear or stangely explained #7
First thanks for this awesome doc, I wish I found it earlier when I was learning about these things !
Regarding DMARC :
If an email passes the SPF and DKIM checks, the receiver then looks at the DMARC rule book to decide what to do with the email
I think it is instead fails the SPF and DKIM checks as both need to fail to DMARC to fail and then check the rulebook to decide what to do (none, quarantine, reject)
In general I think some rewording or clarification may be needed to clarify how DMARC operate based on SPF and DKIM checks :
SPF pass + DKIM pass = DMARC pass
SPF pass + DKIM fail = DMARC pass
SPF fail + DKIM pass = DMARC pass
SPF fail + DKIM fail = DMARC fail, and only in this case you go check the rule book to know what to do (none, quarantine, reject)
