I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

First of all you need to set up a TXT record in DNS,  in the TXT file you will need the following

V=DMARC1 ; p=reject; fo=1; rua=mailto:domain@example.com rf=afrf ; pct =100

where rua= a mailbox for DMARC reports.  

I suggest speaking to the company where you registered your DNS records to confirm with them the settings needed for DMARC,  but that should definitely get you started.

kind regards

WE need for whole domain and not e mail address.

like apple.com

so what should we write:
V=DMARC1 ; p=reject; fo=1; rua=mailto:domain@example.com rf=afrf ; pct =100??

this should be on your external DNS,  the example should be your mail domain i.e rua=mailto:admin@yourdomain.com

you will also need to have the TXT record on your internal DNS where the mailserver resides.
