In the diverse landscape of enterprise integration, email communication remains a critical channel for exchanging business information, notifications, and alerts. Within SAP Cloud Platform Integration (CPI), the Mail Adapter provides a convenient way to send and receive emails as part of your integration scenarios, enabling organizations to incorporate email-based workflows into their digital business processes.
This article delves into the features, configuration, and common use cases of the Mail Adapter in SAP CPI, helping integration developers leverage this component effectively.
The Mail Adapter in SAP CPI is a built-in connectivity option that facilitates email communication by sending or receiving messages over SMTP, POP3, or IMAP protocols. It acts as a bridge between email systems and integration flows, allowing messages to be:
This enables integration flows to trigger actions based on incoming emails or to notify users and systems via outgoing emails.
SAP CPI offers two main types of Mail Adapters:
Sender Mail Adapter: Receives emails from an external mailbox and triggers an integration flow upon arrival of new messages. It supports protocols like POP3 and IMAP for retrieving emails.
Receiver Mail Adapter: Sends emails from the integration flow to specified recipients using SMTP protocol.
To send an email via CPI:
Add Receiver Mail Adapter to your integration flow.
Configure connection details:
Define email-specific properties:
Map the message payload to the email body.
Optionally, add attachments by configuring message headers or enriching the payload.
To receive emails:
Here’s a simple Groovy script snippet to set dynamic email headers before sending via the receiver mail adapter:
import com.sap.gateway.ip.core.customdev.util.Message
def Message processData(Message message) {
message.setHeader("CamelMailSubject", "Order Confirmation - Order #12345")
message.setHeader("CamelMailTo", "customer@example.com")
message.setHeader("CamelMailFrom", "sales@company.com")
return message
}
This script sets the subject, recipient, and sender addresses dynamically before the message reaches the Mail Adapter.
The Mail Adapter in SAP Cloud Platform Integration is a versatile component that enables enterprises to integrate email communication seamlessly into their digital processes. Whether sending notifications or processing incoming emails, the Mail Adapter simplifies these tasks with native support for common mail protocols and flexible configuration options.
By leveraging the Mail Adapter, SAP CPI users can enhance their integration scenarios, enabling timely communication and improved automation across their IT landscapes.
