About the API:  

The Email Authentication API designed to validate and assess the authenticity of email addresses, providing valuable information about their deliverability and security. By analyzing various aspects of email infrastructure and authentication mechanisms, this API provides a holistic approach to email validation, ensuring that only legitimate and trustworthy messages are processed and delivered.

First, the API performs a series of checks to verify the syntax of the email address. This initial validation step ensures that the email conforms to the standard format and structure required for proper communication. By confirming that the syntax is valid, the API helps to avoid errors and inaccuracies that can arise from incorrectly formatted email addresses.

Next, the API checks the domain associated with the email address. This includes verifying the existence and configuration of the domain, as well as checking for any issues that may affect email delivery. By validating the domain, the API helps ensure that emails sent from this domain are legitimate and trustworthy, which improves the overall security of email communications.

In addition, the API performs SMTP checks to verify the availability and functionality of the SMTP (Simple Mail Transfer Protocol) server associated with the domain. This involves establishing a connection to the SMTP server and verifying its responsiveness, ensuring that emails can be successfully sent and received using this server.

While the syntax, domain and SMTP checks may have passed successfully, the API also evaluates the authentication mechanisms implemented by the domain, including SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail). SPF allows domain owners to specify which servers are authorized to send emails on behalf of their domain, while DKIM adds digital signatures to emails to verify their authenticity. In this case, both SPF and DKIM checks have failed, indicating possible problems with email authentication for the domain.

In addition, the API evaluates the provisional deliverability of emails sent to the specified address. This evaluation takes into account several factors that can affect deliverability, such as server configuration, reputation and spam filtering. In this case, the provisional deliverability of the email has failed, suggesting the existence of potential obstacles that may hinder the successful delivery of emails to this address.

In summary, the Email Authentication API provides a comprehensive assessment of email addresses, covering syntax validation, domain verification, SMTP functionality, authentication mechanisms, deliverability assessment and overall quality score. Leveraging this API, companies and organizations can ensure the integrity and security of their email communications, reducing the risk of fraud, spam and deliverability issues.
