Configuring a Custom Domain

Obtaining reliable email delivery requires the implementation of SPF, DKIM, and DMARC. The only way to achieve that in Oracle Transportation and Global Trade Management service is to use an email from address that uses a valid and properly configured Internet Domain. Customer’s often use their company’s domain. It is a best practice to create a mail specific subdomain, perhaps even an OTM mail specific subdomain, i.e. [e-mail]. Using a subdomain will make the configuration of SPF, DKIM, and DMARC easier.

Sender Policy Framework (SPF) is an internet standard for email to reduce spamming and other fraudulent emails by specifically identifying which Internet hosts are allowed to originate email for email addresses within a specific domain name. Since spamming and phishing attacks primarily use forged sender email addresses to lure the victims into opening dangerous emails (since they appear to be from trusted friends, colleagues, or businesses), SPF prevents this by allowing receiving email servers to reject emails that come from hosts that should not be originating emails with certain sender email addresses, therefore preserving the trustworthiness of those email addresses' domains.
