DMARC should always be used in conjunction with SPF and DKIM authentication records. In this context, in order to create a DMARC record, first of all, SPF and DKIM records must be completed in your domain name. You will then need to access DNS management and create a TXT record containing the DMARC record tags.
Thanks to DMARC records, when e-mails that reach e-mail providers and appear to be yours arrive, you are informed about what to do when a message that does not perform authentication checks on these e-mails or does not create authentication rules in your DMARC record. With this advantage, e-mails without a verified identity will not be able to impersonate you or your company.
With the use of this protocol
• Organizations cannot phishing customers.
• It is not possible to misuse your brand name and turn it into fraudulent material.
• The possibility of sending malicious software and spam software to individuals through your brand and organization is prevented.
• In particular, identity attacks can be prevented.
Reports generated by DMARC should be sent to the e-mail address you specified during DMARC registration on a regular basis. In these reports;
• Who sent messages to your e-mail account,
• What percentage of incoming messages passed successfully under DMARC control,
• From which servers the e-mails that produced unsuccessful results in DMARC control came from,
• Information about which DMARC operation performed by e-mails that could not obtain authentication can be obtained.
After these reports are obtained through e-mail accounts, all necessary precautions can be taken against counterfeiting, spam, or phishing attacks, which may be followed by e-mail account owners or account managers.
A sample DMARC record can be used in a practical way over Atak Domain in the line frame presented below.
v=DMARC1; p=reject; rua=mailto:email@example.com, mailto:firstname.lastname@example.org; pct=100; adkim=s; aspf=s
