On October 19, 2021, we have enabled single-sign-on for our Plesk Support Center to provide a seamless login/account experience. This implies that you’ll be able to use a single account across any of our web-facing properties.
If you had already registered your account at Plesk 360 (formerly known as My Plesk) please use one for login. Otherwise please re-register it using the same email address as your existing Zendesk login (support account). It’s essential that you use the same email address on our support center to ensure that your tickets stay attached to the same account.

    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.
