How Does SSL Certificate-Based Signing Work with Emails?

In order to send emails, your email client must first verify that the sender has a valid SSL certificate. In order to do this, the email client and email server need to use SSL certificates. When sending an email with an unknown sender, your email client will look up the public key of the sender’s SSL certificate.
