Question
Why MXToolbox Health Checker reports the following warning for a domain in Plesk?
PLESK_INFO: DMARC Quarantine/Reject policy not enabled
Answer
By default, DMARC policy in Plesk is set to "none" (p= option):
CONFIG_TEXT: _dmarc.example.com. TXT v=DMARC1; p=none
Quarantine/reject policies can be configured if required. These policies request more aggressive protective actions by receivers and should be configured with care.
Additional Information
According to https://dmarc.org/wiki/FAQ:
PLESK_INFO: It is highly recommended that you start with a DMARC “p=none” record in order to monitor the results before moving on to a quarantine or reject policy. The goal of DMARC, when your policy is “p=reject”, is to get the receiver to reject emails that don’t come from your email infrastructure, not to help them make a decision about whether the email you did send is spam.
However, if your policy is “p=quarantine” and you have configuration issues, your mail will be placed in the spam folder because that is what you are asking for.
With a policy of “p=none”, DMARC does not change in any way how your email is handled at the receiver.

What is the solution, if I see this image on https://mxtoolbox.com/ (The results are check on Green)
My dmarc is correct in DNS setting
_dmarc.example.com. TXT v=DMARC1; p=none
I have tried mail-tester.com and I have a 10/10 rating, but it also asks me that the email is not authenticated
Hello Edwynn Flores Martínez - you may ignore this warning. Currently, your policy "none" means if DMARC fail you still recommend accepting message from your domain. MX Toolbox recommends using more strict settings: either “p=quarantine” (will move to SPAM) or “p=reject” (will not accept at all) if DMARC fails.
