What is DKIM Approved List?

DomainKeys Identified Mail (DKIM) is a signature/cryptography-based email authentication that provides a method for validating an email message during its transfer over the Internet.

By validating that the email message comes from the source it is claiming, IMSVA provides spam and phishing protection for your network. Validated email messages are not marked as spam and are not scanned for spam.
