We have a requirement to legalize the spoofing on Oracle Managed Service Mailbox. Can Oracle do this?
Email Deliverability, SPF Record
Oracle Service Cloud, All versions
Oracle is unable to add your mail servers to the Oracle SPF record. The reason behind this is it goes against corporate policy for security. The SPF record allows a sender to send on behalf of someone else; in this case, you are asking to send on behalf of Oracle which cannot be allowed.
In short, the answer is Oracle will not add your mail servers to the Oracle SPF record, adding such an entry puts other customers at risk.
