MAIL SERVER

IIntroduction of the projectntroduction of the project

When you send an e-mail message, your computer transmits it to an SMTP server

using the Internet. The server looks at the e-mail address (like the address on an

envelope), then forwards on it to the recipient's mail server using an application

called Sendmail. If for some reason, the recipient?s e-mail server is inaccessible,

Sendmail periodically re-tries to send the e-mail. If after 4 hours the e-mail has

not been delivered, you receive a notification informing you about the problem. If

the e-mail cannot be delivered even after 5 days, Sendmail gives up and sends you

a failure notification.

When the e-mail is received at the destination mail server, it is stored until it is

retrieved by the addressee. To retrieve your e-mails, your e-mail client (such as

Microsoft Outlook or Outlook Express) connects to the POP3 or IMAP server and

issues a series of commands to download copies of your e-mail messages to your

computer.

E-mails can be sent anywhere in the world to anyone who has an e-mail address.

Almost all Internet service providers (ISPs) offer an e-mail address with every

account.

Initially, when e-mail technology was introduced, only short messages could be

sent. Attachments such as formatted documents, photographs etc could not be

sent. With the introduction of Multipurpose Internet Mail Extension (MIME) and

other encoding techniques, it has become possible to send almost any kind of

attachments.

MAIL SERVER

Objective of the projectObjective of the project

The MailServerComponent implements POP3 and SMTP (core)

servers. It Hand les low level POP3 and SMTP commands and raisesevents according to it. The Mail Server service just handles Mail

Server Component events and does mail retrieving and storing

jobeneral:

Objectives of mail server are:-

SMTP/POP3/IMAP4/Webmail

IP access filtering

User mailbox size limit

Supports XML or MSSQL databases

Nice GUI for administration

Well commented source code included

Why is the particular topic chosen ?

I am an employee of Indian Air Force and working as a technician in IT Cell

since last 10 years. I have been observing the manual work flow of among the

sections. I am deeply concerned with the well being of my organization and

would therefore like to use the computer technology for the improvement of

correspondence and the communication between sections and distant

establishments.

What contribution would the project make and towhom ?

Mail Server will provide fast, reliable and secure correspondence among the sections and

subsections.. The xml and MSSQL database will provide fast mailing service to multiple users

simultaneously. This will minimize the manual correspondence, paper consumption and manpower to

deliver mails. The main advantage of this project to save the precious time to the users for

correspondence.

SECURITY MECHANISMSECURITY MECHANISM

In the software security there are two levels of security.The 1st level of security, which is provided by the FRONTEND and 2nd level of security provided by the databasewhich is being used.

SOFTWARE INTERFACE

- FRONT ENDWe have implementedJavaScript

for all the Client side validations. Client side JavaScript isdesigned to reside inside HTML document & ensure theyrun properly. It is object based, event driven, platform

independent. These are important parts of any Webapplication to implement Client side Validations and theinvalid data is not submitted. The form is not submitteduntil user fills in correct data. It is extremely useful torestrict mistakes by user.

We have implemented Servlets in

between which is fetching the data values given by theuser and storing the input into database (into appropriatetables).Servlets use JDBC-ODBC drivers to makeconnection with database and store data. Servletsprovides support to execute queries via creating objectsof Statement and Connection Interfaces. Servlets areobject byte codes that can be dynamically loaded off the

Internet. Servlets are platform independent, dynamicallyloadable.


26/31

MAIL SERVER

- BACK END We have used Oracle/Accessas the Back end. Oracle Server provides efficient/effectivesolution for major database tech.- Large database and space management.- Many concurrent database users.

- High transaction processing requirement- High Availability- Industry accepted standards- Manageable security- Portability

FRONT END SECURITY:-

This security level is developed or designed by the s/wdeveloper or designer. S/he provides her/his s/w thesecurity for the system, by considering many factors

regarding to the particular s/w.In this software following are used to provide security.


27/31

MAIL SERVER

LOGIN CHECKING:

There are two logins areprovided in this software one for employees and one forapplicants. In order to avail the services of softwareemployees have to provide a valid id and password andonly after entering correct id and password employee willget entry otherwise they will be blocked from accessingany services of this site. Similarly a login check isprovided for user applying for job. In order to enterrecruitment zone user have to enter id and passwordwhich they got after registration , in this way securityhave been provided for both employee section andapplicant section. There is also provision to change thepassword in case password is known by other.
