Email DKIM testing

DKIM (DomainKeys Identified Mail) is an email authentication technique that helps prevent email fraud and phishing scams. By digitally signing email messages, DKIM allows email recipients to verify that the messages were sent from the domain they claim to be from and have not been altered in transit.

DKIM, SPF, and Spam Assassin Validator -

DKIM Validator is a web-based tool that enables you to test your DKIM implementation and check whether your email messages are passing DKIM authentication. This tool is designed to help email senders and system administrators identify and troubleshoot DKIM issues, which can prevent legitimate messages from being delivered to recipients or cause messages to be marked as spam or rejected altogether.

Using DKIM Validator is simple: just enter the email address you want to test and click the "Validate" button. The tool will then retrieve the DKIM signature from the email header and check whether it meets the DKIM specification. The DKIM signature consists of a digital signature and a set of DKIM-specific header fields that provide information about the signing domain, the signing algorithm, and the message headers that were included in the signature.

The DKIM Validator will provide a detailed report on the DKIM signature, including information about the signing domain, the signing algorithm, and any errors or warnings that were detected. If the signature passes DKIM authentication, the report will indicate that the message is valid and can be trusted. If the signature fails DKIM authentication, the report will provide information about the specific DKIM validation error and suggest ways to resolve the issue.
