I configured a "Send Email" process, in the settings, the "From" field, no matter what I input, either a static value, or an item values, such as logged-in user email - &APP_USER. or &P16_EMAIL.), the actual email address in the "From" is always "apexext-noreply@ociapp-notifications.oracle.com", which goes to the spam folder all the time. The Doc seems to say dynamic item value is allowed.
Even though I can fill "Reply to", when the person who received the email hit Reply, a warning comes up: "Caution, you are responding to a different email address..." which is extremely annoying.
How do I configured it so the email "From" is from actual user who is using the app? not some generic oracle address that looks like a spam. Do I have to use pl/sql block with APEX_MAIL.SEND?
