SPF(supported)
DKIM(recommended)
This article covers the SPF and DKIM authentication processes for Xeams 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.
Configuring DKIM authentication for your Xeams emails
Login as admin to Xeams' web interface
Click DKIM under Filter Management
The following page has two sections:
You can specify a spam score on the left hand side for incoming emails. This score is assigned to a message fails a DKIM authentication. This score is only assigned if a signature is found but is invalid.
Specify domains that you would like to sign when sending outbound emails on the right hand side
Preparing your domain for outbound messages
To add your domain, simply specify your domain name along with a selector value. Selector can be any arbitrary value and its purpose is to differentiate multiple SMTP Servers in your company. Consider a scenario where you have two SMTP servers: Xeams and Exchange and outbound emails are sent from both of them. In this case you can use the word "xeams" for the Selector in Xeams and "Exchange" for the other SMTP server.
Xeams automatically creates a pair of Private/Public keys in the background. These keys are saved in $INSTALL_DIR\config\dkimKeys folder. It is strongly recommended you backup this folder. To view the public key value for your domain, click View Details for the desired domain name.
When a domain is added in Xeams, it remains Inactive until the public key is entered in your DNS server. This is done by design to avoid signing an outbound email without a DNS entry.

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