Understanding DKIM email authentication protocol:
What is DKIM?
DKIM stands for DomainKeys Identified Mail (DKIM)
It enables domain owners to automatically "digitally sign" their emails thus confirming the email has actually come from that domain and has not been altered in transit.
Specifically:
a DKIM record stores the domain's public key, and mail servers receiving emails from the domain can check this record to obtain the public key.
An encrypted private key is kept secret by the sender, who signs the email's header with this key
Mail servers receiving the email can verify that the sender's private key was used by applying the public key
How do I set up DKIM?
DKIM is provided by your mail service, not by SuperReach.
Here are some quick links to the main email providers (contact your email provider if you need further instructions)
Do I need to make any changes using SuperReach?
No, as long as your normal day-to-day emailing provider (Gmail, Office365, Exchange etc.) has a valid DKIM record on your domain then SuperReach will be set up correctly.
Where do I check everything is set up correctly?
Luckily several tools on the market will check everything is set up correctly for you. Try some of the links below to get you on your way:
