Declared tags

tag value explanation
v DMARC1 DMARC protocol version.
p reject Apply this policy to email that fails the DMARC check. This policy can be set to 'none', 'quarantine', or 'reject'. 'none' is used to collect the DMARC report and gain insight into the current emailflows and their status.
pct 100 The percentage tag instructs ISPs to only apply the DMARC policy to a percentage of failing email's. 'pct = 50' will tell receivers to only apply the 'p = ' policy 50% of the time against email's that fail the DMARC check. NOTE: this will not work for the 'none' policy, but only for 'quarantine' or 'reject' policies.
