What is DKIM?
DKIM is a way for spam filters and the receiving email address to verify that an email actually comes from the email address listed as the sender of the email. This is done as follows:
When DKIM is enabled, there is a public key in the DNS records of the domain name, and a private key in the mail server. Every email which is then sent will contain DKIM headers, and the receiving mail server will check if the public key matches the DKIM headers of the mail. If the key doesn't match, the email will be rejected or disappear into the spam filter.
