You can use Python to send emails through Email Delivery. Before you can send email you must configure Email Delivery in Python.
These steps assume you are logged into an Oracle Linux instance. Other distributions of Linux may have different commands and file locations.
Configure Python to Send Email Through Email Delivery
To enable Python to test the configuration of Email Delivery:
Ensure Email Delivery is configured to send email. See Getting Started with Email Delivery.
The SMTP credentials are required to configure Python to use Email Delivery. Be sure to note the user name and password when you generate the SMTP credentials.
Ensure Python is installed. The installation process differs depending on which operating system you are using. For example, run the following command to install Python on Oracle Linux:
sudo yum install python3 -y
In a file editor such as vi, create a python script to test Email Delivery.
Run the following command:
sudo vi ociemail.py
In the ociemail.py file, replace the variables with your own values.

To send a test email with Python, run the following command from the directory the script is located in:
