Set up DMARC
Set up DMARC at OVHcloud
Where the OVHcloud DNS editor is, how to write each record in its form and how to check that it has gone in properly.
Where to paste it
“Web Cloud” > “Dominios” (Domains) > domain > “Zona DNS” (DNS zone) tab > “Añadir una entrada” (Add an entry) > TXT type > “Valor” (Value) field > “Añadir” (Add). For SPF and DMARC there are also wizard types (“SPF”, “DMARC”) in the same drop-down
OVHcloud creates some of these records by itself. If one of the same type already exists at that name, edit it: do not add another.
Careful: At OVHcloud, a TXT of more than 255 characters (a 2048-bit DKIM key) only goes in with “Modificar en modo textual” (Edit in text mode).
How OVHcloud writes each name
The same record is written differently depending on the panel. At OVHcloud:
Domain root (SPF)
- Type
- TXT
- Name
(vacío)- Value
v=spf1 include:_spf.google.com ~all
DMARC
- Type
- TXT
- Name
_dmarc- Value
v=DMARC1; p=none; rua=mailto:informes@empresa.example
DKIM (example)
- Type
- CNAME
- Name
selector1._domainkey- Value
selector1-empresa-example._domainkey.empresa.example
Example values: yours depend on which services send with your domain. An SPF copied from somewhere else may leave out your invoicing program.
Check that it has gone in properly
DNS changes take anything from a few minutes to a few hours to show. Once you have pasted the records, run your domain through the X-ray.
