2.1.1 Enable Transport Layer Security (TLS)
Perform the following steps to enable TLS for secure email communication with the SMTP server:
Select the Enable TLS check box.
If you are using a certificate signed by a well-known public CA, select Global Root CAs.
If your organization uses a self-signed certificate issued by an internal Certificate Authority (CA), select Custom CA Certificate.
Click UPLOAD A FILE to upload your CA certificate.
When Fortanix DSM, acting as a client, connects to the SMTP server and receives the server’s certificate, it validates the certificate using the uploaded custom CA certificate.
Click SAVE CHANGES to apply the configuration.
NOTE
When TLS is enabled, Fortanix DSM also validates the SMTP server hostname against the certificate. To disable this, clear the Validate host check box.
