Software platform editor mail system

ABSTARCT :

In this paper, we present the architecture of a new multimedia E-mail system, which has been successfully developed in the Communication and Multimedia Laboratory of National Taiwan University. This prototype E-mail system is fully compatible with traditional Internet E-mails in that the multimedia emails can be sent through Internet. For allowing one to compose multimedia emails, the system provides various editors for editing video, audio, image, graphics, and multilingual (English and Chinese) text. It is currently implemented on SUN Workstations with X-windows and OpenLook as its standard graphical user interface. In order to display video, the workstation are equipped with either an add-on video board or a software-based Codecs. Since its development, the system have been widely used in the National Taiwan University. Experience of users showed that the system is convenient to use and is indeed fully compatible with the traditional Internet E-mails.

EXISTING SYSTEM :

? There exist a number of newsgroups distributed all around the world. These are identified using a hierarchical naming system in which each newsgroup is assigned a unique name that consists of alphabetic strings separated by periods. ? Users can post to existing newsgroups, respond to previous posts, and create new newsgroups. ? If you have never used this folder before, Pine will ask you if you want the folder created; if it already exists, the message will be saved in the existing folder. ? The ability to change a webpages look, content and style once the document has loaded on our demand without changing or deleting everything already existing on the browser’s webpage.

DISADVANTAGE :

? The only problem the user has to face to is the format of the media sections must be confined to a predefined syntax. ? A user can use the preview agent as if the receiver are using this system to read this mail. ? One problem of our preview agent is that the media encoding is time consuming, and a user doesn’t want to take a lot of time in encoding again just for modifying a word. ? The system solves this problem by advancing queuing audio data to avoid voice breaking. ? In this editor, color manipulation on the same image is quite straightforward, but manipulation on multiple images concurrently causes problem

PROPOSED SYSTEM :

• It is a standard protocol used for sending e-mail efficiently and reliably over the internet. • Email phishing is an activity of sending emails to a user claiming to be a legitimate enterprise. Its main purpose is to steal sensitive information such as usernames, passwords, and credit card details. • The purpose of a while loop is to execute a statement or code block repeatedly as long as expression is true. Once expression becomes false, the loop will be exited. • A newsgroup is a discussion about a particular subject consisting of notes written to a central Internet site and redistributed through Usenet, a worldwide network of news discussion groups.

ADVANTAGE :

? If the computer is equipped with special hardware for true color display and real time compression/decompression, such as the Parallax board in our implementation, a hardware based A/V editor is invoked and a peak performance of more than 25 frames per second is achieved. ? It can also be used for communication between people and processes (virtual users) or even among processes themselves. ? The mail message is used for delivering a mail. For compatible reason, MOS E-mail follows MIME (Multiple Internet Mail Extension) standard as its mailing message format. ? One module is used to build, modify, and maintain a letter by adding, deleting, and replacing information in the letter, the other is used to extract information from the received letter.
