DMARC (Domain-based Message Authentication, Reporting & Conformance)

By default, a base DMARC policy is added where if the email fails dmarc, nothing will be done and no email sent with a data report. You then may wish to go to your dns management and edit the dmarc record to add additional functions or add a report email address. The basic functions are listed below.

none No action is taken on messages that don’t pass the DMARC checks by the receiving server. Messages are delivered normally to the recipient.
quarantine Messages that aren’t authenticated with DMARC by the receiving server are sent to the recipient’s spam folder. If the receiving mail server has a quarantine configured, messages might be sent to quarantine, not directly to the recipient’s spam folder.
reject Messages that aren’t authenticated with DMARC by the receiving server are rejected, and never delivered to the recipient. The receiving server usually sends a bounce message to the sender.
rua Report email address is the address to which aggregate reports are sent by domains that have received mail claiming to be from your domain.

An example record could look like this:

v=DMARC1; p=quarantine; rua=mailto:dmarc@yourdomain.com"

ADD DMARC in your control panel

You can add DMARC records from the email security section of your control panel which can be accessed via Email Management.
