This article covers the SPF and DKIM authentication processes for Dualog and how they are managed in Valimail. While only one of the two authentication methods is required for an email to pass DMARC, our recommendation is to configure both whenever possible.

To configure DKIM on outgoing emails, please add the following CNAME record to your DNS server, replacing [domain.com] and [domain-com] as appropriate:

dualog1._domainkey.[domain.com] > s1-[domain-com].dualogmail.com

dualog2._domainkey.[domain.com] > s2-[domain-com].dualogmail.com

Both lines are required, as this allows Dualog to perform key rotation.

Do note, that the > may not feature in your domain management solution; the CNAME records need to point from dualog1._domainkey.[domain.com] to s1-[domain-com].dualogmail.com and from dualog2._domainkey.[domain.com] to s2-[domain-com].dualogmail.com

NOTE: If you manage you domain in Valimail, you will need to add the DKIM key/s on your domain's configuration page in the Valimail platform.
