接上次smtp邮件发送功能，这次用的是JAVAMail， 运行此程序还需三个Java包：mail.jar，activation.jar和htmlparser.jar。 

下面介绍一下JAVAMail中一些基础类，信息如下：

Session类
Session类定义了一个基本的邮件会话。通过该会话可让别的工作顺利执行。Session对象利用java.util.Properties对象获取诸如邮件服务器、用户名、密码等信息，以及其他可在整个应用程序中共享的信息。

Message类
创建要发送的消息。

Address类
一旦创建了会话和消息，并为消息填充了内容，就需要用Address类为您的信件标上地址了。

Authenticator类
与java.net类一样，JavaMail API可以利用Authenticator（验证程序）类通过用户名和密码来访问受保护的资源。

Transport类
发送消息的最后一步操作是使用Transport类。该类使用特定于协议（通常是SMTP）的语言来发送消息。

 

代码示例如下：
