什么是SMTP? SMTP(Simple Mail Transfer Protocol)即简单邮件传输协议,它是一种提供可靠且有效电子邮件传输的协议。SMTP是建模在FTP文件传输服务上的一种邮件服务,主要用于传输系统之间的邮件信息并提供来信有关的通知。
协议结构 SMTP命令是发送于SMTP主机之间的ASCII信息,下面列举了5个常用SMTP指令
HELO <服务商><域名><换行> 与SMTP服务器握手
MAIL <服务商> FROM:<发件人地址><换行> 传送发件人的邮箱地址
RCPT <服务商> TO:<收件人地址><换行> 传送收件人的邮箱地址
DATA <换行> 发送邮件数据,以新行.结束(包括信头与信体)
QUIT <换行> 与SMTP服务器断开连接
信头与信体 在DATA指令所传送的数据中,信头和信体以一个空行分隔,下面列举了部分常用信头
From: 发件人地址
To: 收件人地址
Subject: 邮件主题
Date: 发信时间
MIME-Version: MIME版本
Content-Type: 内容类型
Content-Transfer-Encoding: 编码方式
X-Priority: 优先级
X-Mailer: 代理发信的客户端
通过Socket发送SMTP邮件 1.Base64
Base64内容传送编码被设计用来把任意序列的8位字节描述为一种不易被人直接识别的形式,它要求把每三个8位的字节转换为四个6位的字节,然后在6位字节的高位补两个0,最后组成四个8位的字节。在发送电子邮件时,服务器认证的用户名和密码需要用Base64编码,附件也需要用Base64编码。这种加密方式并非绝对安全,只能做到让人不能直接看出原本内容而已。

2.MIME类型
MIME意为多目Internet邮件扩展,它设计的最初目的是为了在发送电子邮件时附加多媒体数据,让邮件客户程序能根据其类型进行处理。每个MIME类型由两部分组成,前面是数据的大类别,后面为具体的种类。例如:image/bmp、image/jpeg、audio/mpeg
一个用于获取各种后缀名所对应MIME类型的工具类(MIME类型列表本来是存储在XML文件中的,此类的作用是读取XML中的数据,由于本文并不打算介绍XML解析,所以直接将数据写到了代码里)
