What is DKIM record?
DKIM (DomainKeys Identified Mail) is an email verification process designed to identify email spoofing by implementing a mechanism which allows receiving mail exchangers to check the incoming email from a domain which is authorized by the administrators of that domain. This mechanism prevents forged sender email addresses, a technique which is mostly used in email spam and phishing. DKIM permits the receiver to validate that the email which is claiming to come from a specific domain was actually authorized by the administrator of that domain.
