However, traditional mail services is based on client and server, for example, Lotus notes, Microsoft Exchange Server, which have used more resources of the server, thus, affect the capability of server and need high performance of server. Meanwhile, each server needs special client, which increases the cost of developing and managing the system. Based on Web mail server system provides faster, more efficient Web mail services, with the strong capability, the new generation of the Web mail can change the disadvantage of the traditional mail. This paper designs and implements a Web mail receiving-sending system, which is based on browser and server as well as components technology, sending mails through Web and users can use it to send mails with attachments. This paper is divided into four main modules, respectively are First, introduction the background of the selecting the topic as well as the constitution of the system; Second, introduction of work principle, superiors and inferiors and the developing environment of the mail sending-receiving system; Third, introduction of the code procedures and design of the Web page; Last, t
