How to Set Up DKIM for Infradox?
DKIM uses cryptographic signatures and public-key infrastructure to verify that an email message has not been altered during transit and that it truly came from the claimed sender. Email senders can use DKIM to sign their messages by adding a DKIM-Signature header field to the messages. Email receivers can then use the public key published in the DNS to verify the signature and check that the message has not been tampered with.
Although Infradox does not natively support DKIM, it does offer SMTP relaying over any external SMTP server.
You can DKIM sign your message by relaying it over any server that accepts DKIM, such as Gmail.
