Setting DNS records and configuring email authentication for domain
In order to successfully deliver emails to clients, it is important to configure four DNS records: SPF, DKIM, DMARC, and rDNS. These records ensure that emails coming from the domain to the recipient's server are legitimate and not spam or spoofed.
Important: Make sure that the domain is pointed to the panel server at the domain name registrar. Otherwise, the created records will not work and you will have to create or migrate them to the correct name servers.
Configuring SPF
SPF (Sender Policy Framework) — is a DNS record that indicates which IP addresses are authorized to send emails on behalf of your domain. Multiple servers and IP addresses can be specified in one SPF record. For example, when emails are sent from your IP and from the mailing service (ESP), as we do in ispmanager.
To create an SPF record in ispmanager:
1. From ispmanager Main menu navigate to Domain names (DNS).
