When it comes to securing Gmail admin settings, you may not be aware of the matter of configuring your DNS settings properly to prevent spoofing of your domain. By correctly configuring SPF, DKIM and DMARC, your domain will be as safe as ever. Coolhead Tech is here to professionally explain the uses of these features and how to set them up.
Let's begin by explaining these functions.
DMARC, SPF, and DKIM are all security standards followed in GSuite Apps. Google now follows DMARC which allows you to tell how Gmail handles unauthenticated emails coming from within your domain. SPF, or Sender Policy Framework records will allow you to easily identify spam messages for your domain. It is also a type of DNS record that will identify which mail servers are allowed to send an email for your domain. DKIM attaches a new domain name identifier and encrypts the message to validate authorization for the message.
DMARC is an acronym which stands for "Domain-based Authentication, Reporting and Conformance." It is designed to work assist an organization's inbound email authentication process. It helps email receivers determine if the message fits what the receiver knows about the sender.
DMARC's intended use is to follow these standards:
Setting DMARC up is an easy, five step process.
SPF records help identify spammers that send messages using forged envelope senders from your domain. Your users can refer to an SPF record to tell if a message claiming to be sent from your domain is from an authorized mail server.
DKIM allows you to digitally sign your outgoing message headers to prevent spoofing. This practice uses a private domain key to encrypt outgoing mail headers from your domain and adding a public version of the key to the domain's DNS records. This allows receiving servers to verify and decrypt your incoming headers and will be able to tell if the incoming message is really from you and hasn't been been altered along the way.
Keeping your domain and account safe is top priority. When you are finished configuring your DNS settings with SPF, DKIM and DMARC, be sure to monitor your settings on a quarterly basis.
