How to Set Up DKIM for Mailguard?
DKIM is specified in RFC 6376, and it is used by a number of email service providers, including Google, Yahoo, and Microsoft. DKIM is designed to address some of the flaws in the existing email system, such as spoofing, phishing, and message tampering. It allows email senders to digitally sign their messages in a way that can be verified by email receivers. This allows receivers to verify that the message truly came from the sender, and has not been tampered with.
For your domains, ExpressPigeon does support and advise DKIM authentication. For information on how to activate the protocol, contact their support staff directly.
