1. ABSTRACT

This project INTRAMAILING SYSTEM aims of providing a good

communication interface for the organization. It can cut down the time of

employees spend on routine communication tasks. Its successful

implementation makes easy the job of employees in the organization.

The basic problem is that the employees in the organization

communicate or make correspondence only through post, as their units are

located in remote areas. This method of communication is very slow in

nature and it is not reliable.

Therefore the solution for this problem is to develop a

communication channel that meets the need of the organization. Basically,

the computerized solution is for improving the services as well as self-

efficiency of the computer.

The objective of the system is for meeting the needs of the

employees in the organization for communicating with each other within

their units. This application provides basic requirements such as Mail

management, File transfer and instant messaging. It also has enhanced

features like web browsing and utilities.

The Intra-mailing System is very user-friendly application. Only

certain applications like system monitoring instant messaging, chatting

between two users needs a little training.

2. INTRODUCTION

This company has different departments situated in different

locations. It has four offices and three sites (factory). These are situated at

different places and have a minimum distance of 15 Km.

The basic problem is that they communicate or make

correspondence only through post as their units are located in remote

areas. This method of communication is very slow in nature and it is not

reliable.

Therefore the solution for this problem is to develop a communication

channel that meets the need of the organization. Basically, the

computerized solution is for improving the services as well as self-efficiency

of the computer.

This project INTRA MAILING SYSTEM aims at providing a good

communication interface for the organization. It can cut down the time of

employees spend on routine communication tasks. Its successful

implementation makes easy the job of employees in the organization.

This application provides facilities like mails, instant messages and

allows employees to communicate more effectively, and access the

resources they need to maximize their day-to-day productivity. It provides

fast and better access to up-to-date information.

MAIL:

Intra mailing facility allows organizations with simple intranet to

exchange emails internally without the need of an Internet connection, in

which

(a) Usually text is transmitted,

(b) Operations include sending, storing, processing, and receiving

information,

(c) Users are allowed to communicate under specified conditions, and

(d) Messages are held in storage until called for by the addressee.

Intra Mailing System is the system which is used to establish

online communication among the employees of an organization at different

branches and within the organization between the departments. The

employees of the organization can send mails to each other in the working

in different departments at different locations.

The purpose of “Intra Mailing System” is, an employee of a

company can send and receive mails only in that organization’s Local Area

Network or Wide Area Network. It will work like Internet mailing system for

this intranet.

PURPOSE:

The purpose of this document is to describe all the external

Requirements of the Intra Mailing System. It also describes interfaces for

the system it is:

1. To serve as a basis for the users to confirm that the results of the study

phase are acceptable to them.

2. To serve as a basis for the design phase of the project.

3. To serve as a basis for monitoring the progress of the entire project with

reference to the Intra Mailing System.

4. To serve as the basis for the acceptance testing of the application

system with reference to the functional requirements.

5. To document the functions, the proposed system is to perform without

actually going into the implementation details.

SCOPE:

This document describes the requirements of the system. It is meant

for use by the developers, and will also be the basis for validating the

final system. Any

Changes made to the requirements in the future will have to go through

a formal change approval process. The developer is responsible for

asking for clarifications where necessary and will not make any

alterations without the permission of the client.

3. DESIGN PRINCIPLES & EXPLANATION

3.1. MODULES

This project consists of two modules.

1. Administration Module.

2. Mailing Module.

3.2. MODULE DESCRIPTIOIN
