Re: DMARC record

Try to understand it first: https://dmarc.org
The website has detailed introduction, and sample DNS records.

Since you already have SPF and DKIM, a quick DMARC record should be:

v=DMARC1; p=reject; sp=none; rua=mailto:you@your-domain.com

You will receive report from recipient servers which have DMARC software running (e.g. OpenDMARC).

Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?

I have created DMARC record on the DNS server, but when querying from external DNS tools, it says no DMARC found.
I have set the value of p=none for initially getting reports.
