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.
