You can use OpenSSL to examine the certificate chain. Run the following command in a terminal on the Zimbra server: `openssl s_client -showcerts -connect your_zimbra_server:443`. Replace `your_zimbra_server` with the hostname or IP address of your Zimbra server. This will display the certificate chain presented by the server, allowing you to identify any missing or invalid certificates.
