TITLE OF THE PROJECT

WEB MAIL FILTER

Purpose

At present most of the people are using Internet all over the world in their daily life.

One of the main reasons is it provides fastest communication between the people through Emails.

We can receive a no. of mails from our friends, relatives, customers etc.

When we receive a large no. of mails from others, there will be some problems may occur.

SCOPE

WEB MAIL FILTERS for mails is one way to reduce the impact of the problem on the individual user. In its simplest form, this filter is a mechanism for classifying message as either spam or non-spam. This project is for the employees working in an organization.

Major Roles of the Project for mails Avoiding Self-Mails. Checking the mails against UBL (Universal Block List) IP

addresses. Checking the mails against Viruses and keywords specified

by the Administrator. Checking the mails against Subject, From Email ID, and IP

address specified by the user. Checking the mails against the Virus definitions and

keywords specified by the User. Checking the mails against the size limit of the mail

specified by the User. Deleting the mails, which are detected as spam. Showing day-wise report to the users on how many mails

came, how many are filtered by the Email address, and how many are filtered by the subject, etc.

Showing non-spam mails to the user.

Over view of the project

WEB MAIL FILTERS for mails is a fast spam filter that works by learning to recognize the words that are more likely to appear as spam than non-spam. It uses a set of tokens, which are stored in a database, that were taken from the users. When any mail arrives it checks the mail against the tokens specified by the user to whom it comes. If they match then it mark the mail as “spam”, later this mail will be sent to a location where all spam mails are stored. This process segregates spam and non-spam mails and passes them to appropriate locations.

Specify UBL IP addresses and Universal Virus

This module deals with user processing. In this module user can specify what he doesn’t want, such as the mails coming with a specific subject like “free offer”, the mails coming from the specific Email Ids, and the mails coming from the systems with specific IP address etc. The user can also specify virus definitions or keywords to prevent the mails containing those viruses and keywords. If the user wants only those mails whose size is below some limit, then the user can specify the size limit for the mails. Moreover, the user can also edit or delete the filters that are previously specified.

In this module the user can also see the report on the mails came to him every day. This report includes how many mails came to him, out of which how many mails are filtered by the Email addresses, how many are filtered by the subjects, and how many are filtered by the virus definitions etc. In addition to these the user can also see how many non-spam mails are there and he can read those mails.

User:

This module deals with the major task of Mail Filter. It checks the incoming mails for each user against the filters specified by the administrator and by the users. If any match found, then it treats that mail as “spam” and moves that mail to another location. It also stores the details such as Email address, Subject, Date and size of all the mails, both spam and non-spam, in the database for future reference.

Filtering:

SYSTEM ANALYSIS
