DKIM is an email authentication method. When an email is sent using DKIM, a cryptographic digital signature verifies the message's validity. This method creates a unique digital signature for an email message using a hashing algorithm and validates that signature on a mail server using DNS settings.
Please contact Mancloud support for information on how to use DKIM to sign your emails.
