What are the DMARC tags I can use?

A DMARC record is made up of different tags which we'll go over below. 

Required tags:

v            Refers to the DMARC version (DMARC1;)
p            Allows you to define the domain policy (none, quarantine, or reject

Optional tags:

pct   The percentage of emails messages subject to filtering.
  When might I want to use this?
rua   Reporting addresses for aggregate reports. This is where you tell receivers which address
  those reports should be sent to
ruf   Allows you to specify the reporting addresses for forensic/failure reports.
  What are forensic reports?
fo   Allows you to specify the type of failure reports you receive.

  • 0: generate a DMARC failure/forensic report if both SPF and DKIM fail to produce an aligned pass result;
  • 1: generate a DMARC failure/forensic report if either SPF or DKIM produces a result other than aligned pass;
  • d: generate a DKIM failure report if the email's DKIM signature fails validation, regardless of the alignment;
  • s: generate a SPF failure report if the email fails SPF evaluation, regardless of the alignment.
  If you'd like to receive multiple types of failure reports, you can separate each type with a colon:
v=DMARC1; p=reject; rua=mailto:123@report.com; ruf=mailto:123@report.com; fo=0:1:d:s;
aspf   Allows you to specify the alignment mode for SPF. Relaxed (r) or Strict (s)
adkim   Allows you to specify the alignment mode for DKIM. Relaxed (r) or Strict (s).
rf   Forensic report format. The default and currently only supported format is "afrf".
ri   Reporting interval in seconds for aggregate reports. Aggregrate DMARC reports are sent daily
  by default.

  Allows you to specify the DMARC policy for all subdomains.

v=DMARC1; p=reject; rua=mailto:123@report.com; ruf=mailto:123@report.com; sp=none;
