This article covers the SPF and DKIM authentication processes for ClusterCS 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.

Head over to the E-mails tab on the domain you want DKIM installed:

The button will have 3 different colors depending on the state of DKIM for your domain.

It means that DKIM is available for your domain but it needs to be installed on the server.

This will be done automatically if you head over to the Servers tab> Actions > Manage > Scroll down and Save > Execute install and the setup will be configured.

*If our Support team previously configured your DKIM, please submit a ticket and we will assist you with this procedure.

It will generate the DKIM certificate and add it to the list of domains that can send e-mails with the DKIM signature. If you are using ClusterCS’s DNS, the record will be added automatically, otherwise, a page refresh will display it.

It will extend the records you need to add to your DNS provider of choice. The record is type TXT and it needs to be put as ccsmail._domainkey.yourdomain.example

If you require assistance in setting up the DKIM signature for your domain, please contact our Support Team by submitting a ticket.
