Configure SMTP Connection
Set up and test your SMTP connection using an SMTP library or product, such as Postfix or Sendmail, to send email through Oracle Cloud Infrastructure Email Delivery.
Open Email Configuration to access SMTP sending information to configure the connection in your system. Open the navigation menu and click Developer Services. Under Application Integration, click Email Delivery. In the Resources menu, click Email Configuration. The following information is displayed:
- Public Endpoint: The public endpoint used to send email to for this region.
- SMTP Ports: The SMTP ports used to accept email. Email Delivery supports TLS on port 25 or 587.
- Security: This field indicates if TLS, the standard means of performing
encryption in transit for email, is being used. Customers must encrypt email while
it is in transit to the Oracle Cloud Infrastructure
Email Delivery service.
Encrypted emails are protected from being read during transit. Important
Java applications (including JavaMail) must be updated to the latest version to ensure the latest protocols, ciphers, and security patches are in compliance with Oracle's supported security policies and ciphers.

TLS Requirements
Oracle maintains strict security policies and only accepts email traffic using Transport Layer Security (TLS). Use of TLS 1.2 is mandatory to send email using Oracle Cloud Infrastructure.
The approved TLS 1.2 ciphers are:
- TLS_DHE_RSA_WITH_AES_256_CBC_SHA
- TLS_DHE_RSA_WITH_AES_256_CBC_SHA256
- TLS_DHE_DSS_WITH_AES_256_CBC_SHA256
- TLS_RSA_WITH_AES_256_CBC_SHA
- TLS_RSA_WITH_AES_256_CBC_SHA256
- TLS_DHE_RSA_WITH_AES_128_CBC_SHA
- TLS_DHE_DSS_WITH_AES_128_CBC_SHA256
- TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
- TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
- TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
- TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256
- TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256
