  • There are POP3(Post Office Progocol 3) and IMAP4(Internet Message Access Protocol 4) for E-Mail service of wire Internet For mobile e-mail service that use wireless Internet, must use exclusive use mobile e-mail server in the case of POP3 e-mail or flow e-mail conversion and because e-mail is kept in sever side with remote file server in case of IMAP4 mail that is used by Web-Mail, utilization of mobile e-mail service is difficult by mobile client who there is no IMAP4 rules. This thesis embodying e-mail extraction engine for mobile that do to design markup language converter of XML base, and use Web-Mail of recently been generalizing IMAP4 base in mobile, presented mobile e-mail service method to do so that can use Web-Mail that is based on IMAP4 as well as POP3 mail service in mobile environment.

  • Web-Mail Services are implemented with SMTP and POP3 in these days. These web mail services provide not only the basic sending and receiving functions but also additional functions for user. However, the sent and received data are stored in the web mail server. So general web mail users can't process their mail data if they have not access ID for the web mail server. In this paper, we design and implement WMIS (Web Mail Integration System) using XML. In the proposed system, mail data and user's environments in the old web mail system are transformed into XML documents and inserted into database. In order to store XML data into database, we use dynamic document processing method and analyze XML file by record unit. When the users change their mail accounts, they easily can establish the web environments and their mail data. Because the transformed XML document is converted into WML easily, the WMIS can reduce development cost, labors and time.

  • In existing internet, e-mail protocols including POP3 and IMAP4, provide e-mail services fir exchanging messages with texts, hypertext and images as well. For the e-mail services in wireless mobile network, mobile e-mail service providers have to install a mobile exclusive e-mail server or have to convert e-mail to mobile exclusive e-mail with wireless application format in case of POP3 protocol. In the e-mail service of IMAP4 case known as web-mail, it is difficult to view e-mail directly from server without IMAP4 mobile client because e-mail is stored in mail server side with remote file server. In either case, it also has the problems of viewing the e-mail of hypertext and image information at mobile. This paper provides e-mail extraction engine with image and hypertext conversion facilities that can be applied in wireless mobile internet and it is optimized in mobile communication environments such as a small display, small size of memory with web-mail protocol based on IMAP4 as well as POP3 mail protocol.

  • Web-mail system is worthy of note as a next generation e-mail system for its mobility and easiness. But many web-mail system does not have any kind of security mechanism. Even if web-mail system provides security services, its degree of strength is too low. Using these web-mail systems, the e-mail is tabbed, modified or forged by attacker easily. To solve these problems, we design and implement secure web-mail system based on the international e-mail security standard S/MIME in this thesis. This secure web-mail system is composed of server system and client system The server system performs basic mail functions - sending/receiving the mails, storing the mails, and management of user information, etc. And the client system performs cryptographic functions - encryption/decryption of the mails, digital signing and validation, etc. Because client system performs cryptographic functions this secure web-mail system gives its reliability and safety, and provides end-to-end security between mail users. Also, this secure web-mail system increase system efficiency by minimize server load.

  • A web based E-mail system consists of serves which supply mail accounts and service, and clients which take part of interfacing with users. The web browsers such as Netscape Navigator and Internet Explorer are the popular clients. Users who cannot afford to get an E-mail id in general mail servers are, therefore, able to reach a e-mailing service in the web environment by using client programs in connection with a mail server. Although the quality of service has been upgraded a lot in recent days, it doesn't provide with satisfactory services anymore. In this paper, we intend to design a mail agent system based on the web environment. Through this system we could reach a convenient user interface based on Internet Explorer and could easily access administratory environment on the basis of NT Server 4.0. Using the service engine dominent in mail agent system, it could provide with convenient user interfacing tools like responding the absence of users, mail filtering and refusing messages, etc. And it would ultimately make possible a constant system security, by preventing system failure phenomena caused by extraordinary uses beyond its capability.

  • Now is the time for web-based video e-mail system because of world wide use of internet. But video data is so large, then data compression is much needed for transmission by web. In this paper, my colleagues and I implement full motion video e-mail system using MPEG-4, the international standards for audio-visual data. This video e-mail system is made of web-based active-X control, so easily accessible by web, and applies real-time audio-video compression. It's possible for everyone to send video e-mail for free to everywhere in the world if this system is used. The main application areas of this system are multimedia mailing service, web-based video advertisement, remote education, remote medical service and shopping mall construction, etc.

  • 유선 인터넷 망의 Mail 서비스에는 POP3(Post Office Protocol 3)규약과 IMAP4 (Internet Message Access Protocol 4)규약을 기반으로 하는 Mail 등이 있다. 무선 인터넷을 이용한 모바일 메일 서비스를 위해서는, POP3 Mail의 경우 전용 모바일 메일 서버를 이용하거나 메일 변환을 거쳐야 하고. Web Mail로 이용되는 IMAP4 메일의 경우에는 원격 파일 서버와 같이 서버 측에 메일이 보관되므로 IMAP4 규약이 없는 모바일 클라이언트로는 모바일 메일 서비스의 이용이 곤란하다. 본 논문에서는 XML 기반의 마크업 언어 변환기를 설계하고. 최근 보편화되고 있는 IMAP4 기반의 Web Mail을 모바일에서 이용할 수 있도록 하는 모바일용 메일 추출 엔진을 구현함으로써, POP3 메일 서비스뿐만 아니라 IMAP4를 기반으로 하는 Web Mail을 모바일 환경에서 이용할 수 있도록 하는 모바일 메일 서비스 방법을 제시하였다.

  • The paper is a design and implementation of the Hybrid Messaging System as integrating electronic mail system and common mail system based on PKI(Public Key Infrastructure), A user writes mail through Web Browser and sends the mail to Web Server. CGHCommon Gateway Interface) program sends the mail that was received through the Web Sever to Post Office Electronic Mail Server using SMTP(SimpleMail Transfer Protocol), The End Process program of the Hybrid Messaging System in a Post Office fetches the mail from the Post Office Electronic Mail Server using POP3 (Post Office Protocol 3), prints it and deliver it to recipients, Also, the Hybrid Messaging System is able to sign the mail with a sign private key that the Certificate Authority publics for users and encrypts the mail with a public key of the Post Office Web Server.

  • Many more use e-mail purely on a personal basis and the pool of e-mail users is growing daily. Also, the amount of mails, which are transmitted in electronic commerce, is getting more and more. Because of its convenience, a mass of spam mails is flooding everyday. And yet automated techniques for learning to filter e-mail have yet to significantly affect the e-mail market. This paper suggests Web Mail Filtering Agent for Personalized Classification, which automatically manages mails adjusting to the user. It is based on web mail, which can be logged in any time, any place and has no limitation in any system. In case new mails are received, it first makes some personal rules in use of the result of observation ; and based on the personal rules, it automatically classifies the mails into categories according to the contents of mails and saves the classified mails in the relevant folders or deletes the unnecessary mails and spam mails. And, we applied Bayesian Algorithm using Dynamic Threshold for our system's accuracy.
