I have few questions about above mechanisms: 1. Where are stored mails when DMARC is set to quarantine and SPF or DKIM will fail for specific email message? Are they going to Spam in mailbox? 2. When I set SPF as softfail and also add DKIM to dons zone of specific domain then both mechanisms give true and DMARC, when run, pass the mail. Am I right? 3. What is main idea of setting soft fail "~all" if each mailserver can pass this setting?
