MODULE DESCRIPTION:

The SMTP Mail Server VB.Net project consists of the following five modules:

1.User administration.

2.Mail organization.

3.Message composition.

4.Message Address list

5.Message Deletion.

Mail Organization Module

This module deals the organization of mails. When the users are created ,a directory with     the user-id as its name should be created along with four sub directories:

Inbox, Compose and Address list.

The Compose box contains the transmitted messages.

The inbox contains all the incoming messages.

The Address list box contains the users details that can be recovered.

Message Composition Module

This module deals with composing messages . It forms the information such as:

“From” (Sender’s user-id), “To”(Receivers user-id), “Date of Transmission”, “Subject”, “Message” and “Attach” to be transmitted. The message is converted and stored as a file in the outbox of   the sender before it is being transmitted. The file name should be the combination of the  sender’s user-id and receiver’s user-id.

The contents of the file should follow the following format:

• From:
• To:
• Date:
• Subject:
• Message:
• Attach:

The module prompts the user for the file information that has to be transmitted. The messages

can be user-typed information at runtime or messages that are part of the file. The user is supposed to type in the message or specify the file name. Other information such as from whom, the message is transmitted, to whom, it is being transmitted, date of transmission are also accepted.

This information is stored in the following format:

• From:
• To:
• Date of Transmission:
• Subject:
• Message:
• Attach:

This information is stored in a file that has the name of the user-id concatenated along with the name of the receiver’s user-id . The composed messages is then stored in the outbox of the sender. This file remains till it is selected and transmitted by transmit module. Every user’s composed message is stored in the user’s outbox.

Message Address list Module

This module is responsible for having all the personal users addresses which have been stored in the user’s Address. Once the user create all the contents of the file are displayed in the view file. These Contents are, from whom the message has been sent, date on which it was received, subject and the message.
