Why is my DNS record not found?

I check my site at mxtoolbox.com and get some DNS errors. Two of these errors say: "DNS record not found." One has dmarc as a category and the other is a spf category.

My questions:

  • Does it harm my site?
  • How can i fix this?

My website is http://www.zilvertron.com

Thank you for your time!

No, none of these things will harm your site, although they can cause problems with sending email if recipients sharply evaluate the spam management application.

DMARC spf , "" , - , .

/ , dns , , . Spf - , DMARC/DKIM .
