The Email API provides functions to create, set properties and send email.

Overview

The Email API provides functions that prepare and send email messages. This API allows email message creation, setting message properties and sending as well setting up to be notified when the email message has been sent.

Email, short for electronic mail, is a method of exchanging digital messages. This API allows you to send email using SMTP. Simple Mail Transfer Protocol (SMTP) used for sending email via Internet is described in RFC5321/5322 standards.

The Email API consists of functions that:

Set the subject, body and recipients of an email message
Set the file path for attaching files to an email message
Send an email message
Register/unregister a callback function to be called when the sending process is complete, whether it is sent successfully or not

Related Features

This API is related with the following features:

http://tizen.org/feature/email
It is recommended to design feature related codes in your application for reliability.
You can check if a device supports the related features for this API by using System Information, thereby controlling the procedure of your application.
To ensure your application is only running on the device with specific features, please define the features in your manifest file using the manifest editor in the SDK.
More details on featuring your application can be found from Feature Element.

Email sending is asynchronous and the application should not wait for the result. Not only may the process be slow (connections to be established and so on), but even if the mail server is not available a message send may not be a failure, if there is a spooling mechanism. Instead, the callback function is used to receive status. In addition, note that once email_send_message() is called, the message contents are out of the application's hands. Even if the message appears not to have finished sending, it can no longer be modified.
