  Hello :) There is no native support for DMARC at this time, but you can try manually adding the required TXT record. Google offers some instructions on this here:

  After some experimenting I found that in the WHM DNS Zone Editor you need to set the domain to _dmarc the RR to TXT and input the dmarc record something like (without escaping any ; or @) "v=DMARC1;p=none;pct=100;rua=mailto:serveradmin@mydomain.com;ruf=mailto:serveradmin@mydomain.com"
  To test you have the proper structure you can check with $ dig +short txt _dmarc.mydomain.com should return "v=DMARC1\;p=none\;pct=100\;rua=mailto:serveradmin@mydomain.com\;ruf=mailto:serveradmin@mydomain.com"
  or $ nslookup > set type = TXT > _dmarc.mydomain.com will return something like _dmarc.mydomain.com text ="v=DMARC1\;p=none\;pct=100\;rua=mailto:serveradmin@mydomain.com\;ruf=mailto:serveradmin@mydomain.com"

  There are a few different formats you can use. You can use the one referenced earlier in this thread: Dmarc authentication The following URL is useful if you want to understand exactly how DMARC records work: Add a DMARC record - Google Apps Administrator Help Thank you.
