Set a DMARC policy
Before activating a DMARC policy for your domain, make sure that the SPF record is set correctly.
Setting up a DMARC record requires you to choose how suspicious emails are handled. Emails are considered suspicious when they don't conform to the domain's SPF and DKIM settings.
Policy options (p) are:
- none: no action is performed on the message;
- quarantine: messages are marked as spam and moved to the Spam folder of Qboxmail;
- reject: the recipient server is required to reject the message.
We recommend activating DMARC policies gradually, starting from 'None', followed by 'Quarantine' and 'Reject'.
An example of DMARC record could look this:
v=DMARC1; p=quarantine; rua=mailto:rua@dmarc.qboxmail.com; ruf=mailto:ruf@dmarc.qboxmail.com
This record instructs recipient servers to mark suspicious messages as spam and sends the daily report to the address rua@dmarc.qboxmail.com.
To apply the above record, it is necessary to create a TXT type record in the domain DNS:
| Record Name | Record Type | Value |
|---|---|---|
| _dmarc. | TXT | v=DMARC1; p=quarantine; rua=mailto:rua@dmarc.qboxmail.com; ruf=mailto:ruf@dmarc.qboxmail.com |
Qboxmail interprets and applies the DMARC policies set by the sender but does not include the sending of daily XML reports.
