Is it possible to have DMARC working in OVH mxplan mailing list?
What mailing list software OVH operate and what version?
There is long answer for question "I operate a mailing list and I want to interoperate with DMARC, what should I do?" in DMARC.org FAQ page.

Hi,<br /><br />Google has a good website called "Help prevent spoofing, phishing, and spam"<br />with topic number "9061731" that should help you set up DMARC, SPF and DKIM<br />and if you search for "Advanced Gmail security" they have a good article on "Increase email security with MTA-STS and TLS reporting".<br /><br />You did not mention what plan are you on with OVH as this will depend on which of these futures you can set up as not all are available on the free MXPLAN 1 hosting.<br /><br />My DMARC in TEXT format is as following:<br />_dmarc IN TXT "v=DMARC1; p=reject; ruf=mailto:ruf@domain.name; rua=mailto:postmaster@domain.name, mailto:dmarc@domain.name; pct=100; adkim=s; aspf=s"<br /><br />I also have changed my SPF to:<br />IN TXT "v=spf1 mx a include:mx.ovh.com -all"<br />How strict should be the servers treating the emails?: FAIL "-" NOT COMPLIANT WILL BE REJECTED.
