This article covers the SPF and DKIM authentication processes for Atlassian Cloud 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.

In order to enable DKIM signing for your domain, you will need to add the following two CNAME records in your DNS.

s1._domainkey IN CNAME s1._domainkey.atlassian.net.

s2._domainkey IN CNAME s2._domainkey.atlassian.net.

Important: If you manage DKIM for your domain in Valimail, you will need to add the 2 CNAME DKIM keys on your domain's Configuration page in Valimail Enforce.

You can also find the instructions on how to set up DKIM and SPF for Atlassian Cloud, here.

Once you establish that Atlassian Cloud is an authorized sender for your domain, you will need to add the service in your Enabled Senders.
