What is email authentication? How does it work?
Email authentication is the process that takes place before the user gets the email. The main aim of the process is to ensure that the incoming message is authentic and not altered in any way on its route from the sender's outbox to the recipient’s inbox. While it may seem like a simple act, the process is quite complicated and involves a fair share of instruments to be carried out precisely. Those instruments are called protocols.
When the authentication email process is launched, all the messages sent from a given domain or subdomain are checked. The authentication protocols represent a set of rules encoded in Domain Name System records (DNS) so that both the sending and the receiving servers can communicate with one another, either confirming or discarding the reliability of the message. Usually, the process looks the following way:
The sending domain defines a set of authentication rules for all the messages sent from it or on its behalf.
- The preset rules are published in DNS records.
- Receiving servers use the published rules to confirm the authenticity and deliver the messages.
- If the receiving server fails to authenticate the email – it is either rejected or placed in quarantine.
There may be slight deviations from the mentioned process since every protocol is special, but the general outline is mainly preserved.
