Although there are other options in DMARC that are not mentioned here, these are the most common options for forming your DMARC txt record in DNSAlthough there are other options in DMARC that are not mentioned here, these are the most common options for forming your DMARC txt record in DNS
Here’s how you add a DMARC text record for your domain in the CloudFloorDNS control panel:
NAME      TYPE        DATA
_dmarc      TXT        “v=DMARC1; p=none; pct=100; p=quarantine; rua=mailto:domains@YourDomain.com;”
Domain is the domain you want to protect. By default, the record protects mail from the domain and all subdomains. For example, if you specify _dmarc.YourDomain.com, then DMARC protects mail from the domain and all subdomains, such as testing.YourDomain.com or development.YourDomain.com
TTL should always be the equivalent of one hour (3600 seconds)
pct=100 indicates that this rule should be used for 100% of email.
Policy specifies what policy you want the receiving server to follow if DMARC fails. You can set the policy to none, quarantine, or reject.
