摘要

 電子郵件在當(dāng)今社會(huì)中扮演了一個(gè)很重要的角色。越來(lái)越多的人在使用它。而且用它的人數(shù)勢(shì)必會(huì)繼續(xù)增加。雖然，現(xiàn)在已經(jīng)有很多的郵件收發(fā)軟件例如著名的FoxMail 但是對(duì)于大多數(shù)的非專業(yè)的人來(lái)說(shuō)它還是有點(diǎn)難度稍嫌負(fù)責(zé)。因此，我們就利用SMTP和Pop協(xié)議從底層開(kāi)發(fā)了這個(gè)軟件。SMTP全稱是簡(jiǎn)單郵件傳輸協(xié)議，它專門用來(lái)發(fā)送郵件用的。Pop全稱是郵局協(xié)議，是專門用于接收郵件的。我主要是負(fù)責(zé)如何實(shí)現(xiàn)發(fā)送郵件功能的。MailSend命名空間是我整個(gè)程序的核心。它包括兩個(gè)類。在SmtpMail的類中包含了一個(gè)SendMail的方法，它從底層詳細(xì)地實(shí)現(xiàn)了和服務(wù)器的交互操作。你既可以用它發(fā)送一個(gè)純文本郵件，也可以發(fā)送一個(gè)帶有附件的郵件，理所當(dāng)然地，你也可以使用不同的SMTP服務(wù)器。經(jīng)過(guò)測(cè)試，證實(shí)此軟件是一個(gè)支持多收信人，多附件的群發(fā)軟件。雖然它沒(méi)有FoxMail那么強(qiáng)大的功能，但是它容易掌握和使用。

Abstract

 E-Mail play a very important role in modern times.More and more people are using it,and the number of it will larger and larger.Though there are a lot of software for sending and receiving letters such as FoxMail which are also multifunctional,it is difficult and complicated to the Most of people who are curbstone.For this reason,we do this software with the rock-bottom protocol of SMTP and Pop. The full name of SMTP is Simple Mail Transfer Protocol.It is Used to sending letters.The full name of Pop is Post Office Protocol which is Special to receive letters.I basically take charge to how to realize the function of sending letters. A namespace which is named MailSend is the soul of my programe.It includes two classes.A method named sendmial which realize the fuction step by step belongs to the class of SmtpMail. It detailedly note the track of client exchange to the server. You can use the software to send either a text E –Mail or a textE-mail with Attachments.You also can Send a letter to many addressee. In the nature of things,you can use a different SMTP service. The software I did support multiletters and multisender after I test.It is simplier than FoxMail and other professional softwares,but it is easy to hold and use.
