S/MIME email support
Secure/Multipurpose Internet Mail Extensions (S/MIME) sign email with a digital signature that verifies where the email came from. If the email client supports it, S/MIME can also encrypt the email.
Enable S/MIME for Apple devices (iOS and macOS) through a configuration profile payload. The payload must include a third-party security certificate for signing and encryption. Self-signed certificates aren't supported.
•iOS S/MIME support is configured in the Mail section of a Mobile iOS configuration profile.
•macOS S/MIME support is configured in the Mail section of a macOS configuration profile.
