To create a DMARC entry

How do I create a DMARCA DMARC record is one of the lines in your website's DNS records. It was developed to make it more difficult for spammers to "spoof" your domain, which means that they pretend to use your domain as the real sender. DMARC really helps ensure that phishing emails and malware cannot be sent from your email address.

pct	optional	% of messages that were subjected to filtering	pct=20
rua	optional	Report URI of aggregated reports	rua=mailto:[email protected]
call	optional	Addresses to which message-specific forensic information is to be reported (comma-separated plain text list of URIs).	ruf=mailto:[email protected]
rf	optional	Format for message-specific forensic information reports (comma-separated plain text value list).	rf=afrf
aspf	optional	Alignment mode for SPF	aspf=r
adkim	optional	Alignment mode for DKIM DKIM (Domain Keys Identified Mail) is a method of e-mail authentication that uses a signature to make it difficult for the sender to falsify.

Only the tags v (version) and p (policy) are required. There are three possible policy settings or message dispositions available:

• none policy: Do not take any action. Only log the messages concerned on the daily report.
• quarantine policy: Mark affected messages as spam.
• reject policy: Cancels the message on the SMTPSimple Mail Transfer Protocol (SMTP): SMTP is another of the three email protocols. It is most commonly used for sending email from an email client through an email server. This protocol uses TCP for the administration and delivery of the e-mail. layer.

The alignment mode(aspf / adkim) refers to the accuracy with which sender entries are compared with SPF and DKIM DKIM (Domain Keys Identified Mail) is a method of e-mail authentication that uses a signature to make it difficult for the sender to falsify.
