Operating system CentOS Linux 6.7 Webmin version 1.760 Virtualmin version 4.18 Authentic Theme
DMARC Fails using mxTools https://mxtoolbox.com/dmarc.aspx using both the sub domain and domain.
Using Webmin, logged into the web1.xxx-xxxxxxxxts.com server I went to
Webmin > Servers > Bind DNS Server > Down under Existing DNS Zones > Click on xxx-xxxxxxts.com MASTER Type > Now in Edit Master Zone and DMARC is listed > Click on that
and the record form comes up. into that I put the following record _dmarc TXT ("v-DMARC1;p=none;rua=mailto:xxxxx@xxx-xxxxxxxts.com")
We have: xxx-xxxxxxxxts.com ---> main domain where DMARC record is set
We are using two servers: eml1.xxx-xxxxxxxxts.com ---> email server web1.xxx-xxxxxxxxts.com ----> web server
When I go to mxTools and test DMARC for both xxx-xxxxxxxxts.com and eml1.xxx-xxxxxxxxts.com
DMARC does not pass, it fails. Is this because of confusion about the sub-domain? Do I have to put a DMARC record into the sub-domain too?

I can give the full url if it is ok to do so.
Thank you for any help..
TPN Solutions Peter Knowles, just advised that because I used Webmin, and had not told Bind DNS to reload the record, so the DMARC record was entered but not loaded.
He suggested I use Virtualmin for that because it is for guys like me and not as complex.
Virtualmin > Domain > Server Configuration > DNS Records
Now I can see our DMARC record passes in Returnpath tool https://stopemailfraud.returnpath.com/dmarc/
Peter advises that the Dmarc record is not used that much by the other mail servers yet.
Thank you Peter!
