ONTAP-30149：機能要求：ONTAP AutoSupport SMTP Authentication over TLS（STARTTLS）が9.15.1でサポートされるようになりました

問題

Prior to 9.15.1, ONTAP AutoSupport over STARTTLS was not supported.
Starting in 9.15.1 ONTAP has added support for STARTTLS from the node to your mailhost
[system node autosupport modify|https://docs.netapp.com/us-en/ontap-...ml#parameters]  [-smtp-encryption {none|start_tls}] - SMTP Encryption --Use this parameter to specify the encryption protocol used to deliver AutoSupport messages to the configured mail servers. When this parameter is set to none , the SMTP AutoSupport message is not encrypted. When this parameter is set to start_tls , the existing plaintext channel is upgraded to a TLS encrypted channel using the STARTTLS protocol. If the TLS connection fails, there is no fallback to plaintext transfer. The default is none .
