This provides the most robust features. Note the following:

As a general rule, you should use SMTP only if HTTPS/HTTP is not allowed or unsupported for some reason. Note the following:

When using either HTTP or SMTP, all traffic is unencrypted and can be easily intercepted and read. When using HTTP, you should always configure the protocol to also use TLS (HTTPS).

The following ports are typically used for the secure versions of these protocols:

With TLS, the certificate downloaded from the server is validated by ONTAP based on the root CA certificate. Before using HTTPS or SMTPS, you need to make sure the root certificate is installed in ONTAP. See Install the server certificate for more information.

Regardless of the protocol used to deliver AutoSupport messages to us, you can also send a copy of each message to one or more local email addresses. For example, you might send messages to your internal support organization or a partner organization.

Depending on your network configuration, the HTTPS protocol may require additional configuration of a proxy URL. If HTTPS is used to send AutoSupport messages to our Support and you have a proxy, you must identify the URL for the proxy. If the proxy uses a port other than the default (port 3128) you can specify the port for that proxy. You can also optionally specify a user name and password for proxy authentication.
