Vanity Email SPF Policy Update
Content (please ensure you mask any confidential information):
1. Is updating “SPF” the only way for Oracle sending an email on behalf of customer domain when using vanity email?
2. How can we prevent other customers of OCI sending email on behalf of our customer domain? Does Oracle SMTP server have authentication for customer or dedicated IP for a particular customer?
3. Can you share manual for setup SMTP?
Use Case and Business Need (Required):
Our customer has security concern for email spoofing if any other organization uses the same vanity email. Also, instead of updating SPF policy can this be done in a different way.
