What is the domain that we should add to the SPF policy of our domain?
In our test instance, the emails arrive from @workflow.mail.us2.cloud.oracle.com, is this the only domain that we must register, several or a suffix of it? The same question for the production instance is added to the fact that no notifications have been received from this instance because they are disabled so as not to cause phishing alerts internally and the domain is unknown.
How many hops (redirects) does the domain you want to add to the SPF make? We support a maximum of 10 hops.
