DMARC Configuration
DMARC is a domain-based reporting, and compliance authentication standard. This is implemented to ensure that a legitimate email is properly authenticated based on established DKIM and SPF, which may block any fraudulent activity that comes from domains under the control of the organization.
To configure DMARC for using with DANAConnect you must first contact your Account Manager and ask them to provide an email address for receiven the rua records and another email address for receiving the ruf records. Onece you have this addresses the DNS administrator of your domain must follow the next steps:
Add the the DNS txt record for the domain to be configured:
_dmarc IN TXT "v=DMARC1; p=none; sp=none; rua=mailto:sudominio@danaconnect-dmarc.com; ruf=mailto:sudominio@danaconnect-dmarc.com; rf=afrf; pct=100; ri=86400"
1.1. To configure in monitoring mode add:
_dmarc IN TXT "v = DMARC1; p = none; rua = mailto:cliente-rep@danaconnect-dmarc.com; ruf = mailto:cliente-for@danaconnect-dmarc.com; pct = 100; adkim = r; sp = none; fo=1; ri=43200"
1.2. To configure in quarantine mode:
_dmarc IN TXT "v= DMARC1; p = quarantine; rua = mailto: cliente-rep@danaconnect-dmarc.com; ruf = mailto: cliente-for@danaconnect-dmarc.com; pct = 100; adkim = r; sp = quarantine; fo = 1; ri = 43200"
In addition, you must register the CNAME for the DANAConnect platform:
dana IN CNAME bounce.email-platform.com.
It is really important to not duplicate the DMARC DNS record but to edit it adding the information needed. Having two o more records would make DMARC policies fail.
