<h1 class="pg">Introduction</h1>
	<h2 class="pg">Overview </h2>
Electronic mail, most commonly abbreviated email or e-mail, is a method of exchanging digital messages. E-mail systems are based on a store-and-forward model in which e-mail server computer systems accept, forward, deliver and store messages on behalf of users, who only need to connect to the e-mail infrastructure, typically an e-mail server, with a network-enabled device for the duration of message submission or retrieval.

	<h2 class="pg">Purpose of Programming Guide</h2>
This document is mainly aimed at the core functionality of the Email Service.  The EMail Service component is implemented by Samsung to provide EMail service to applications that make use of EMail Engine. Email Engine provides functionality for the user like composing mail, saving mail, sending mail, and creating user mailbox according to the settings. Mobile subscribers can use the Email Engine to perform storage opearations such as save, update, get, delete and transport operations such as send, download and other email operations.

This programming guide is prepared for application developers who will use the email-service. It contains: 
- List of features offered by email-service
- Information on How to use APIs provided by the email-service
- Examples 

	<h2 class="pg">Target Domain / Application</h2>
The Email Service Layer can be utilized by any component in the application layer which allow the end user to perform the email related operations such as save, send, download email message and others.

For Example, the Email Service APIs shall be invoked by 
@li Multimedia application when user opts to send media file through email 
@li Email application when user tries to send an email message

Whenever an application wants to use email-service, it will call APIs from Email MAPI layer. Email MAPI layer APIs will internally call APIs provided by email framework module.

- Alice composed a message using MUA (Mail User Agent). Alice enters the e-mail address of her correspondent, and hits the "send" button.
- MUA format the message using MIME and uses Simple mail Transfer Protocol to send the message to local MTA (Mail Transfer Agent) i,e smtp.a.org run by Alices ISP (Internet Service provider).
- The MTA looks at the destination address provided in the SMTP protocol i,e bob@b.org. An Internet e-mail address is a string of the form localpart@exampledomain. The part before the @ sign is the local part of the address, often the username of the recipient, and the part after the @ sign is a domain name. The MTA resolves a domain name to determine the fully qualified domain name of the mail exchange server in the Domain Name System (DNS).
- The DNS Server for the b.org domain, ns.b.org, responds with an MX Records listing the mail exchange servers for that domain, in this case mx.b.org, a server run by Bob's ISP. 
- smtp.a.org sends the message to mx.b.org using SMTP, which delivers it to the mailbox of the user bob. 
- Bob presses the "get mail" button in his MUA, which picks up the message using the Post Office Protocol (POP3).
