Important: outbound delivery

Oracle Cloud often blocks outbound port 25. Direct delivery to Gmail/Outlook can time out. Submission from your phone/Thunderbird on port 587 still works for authenticated clients; for reliable bulk outbound, configure a relay (Gmail App Password, SendGrid, Amazon SES, etc.) on the VM.
