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:email@example.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.
