（1）用javaemail发送邮件&需要mail.jar包和activation.jar

在email.html页面输入内容提交到JavaMail.jsp页面处理和发送
1、配置发件人的服务器地址

2、配置发送人的邮箱
3、配置发送人的用户名密码

email.html页面代码：

<html>
<head>
<title>JavaMail.html</title>
<meta http-equiv="Content-Type" content="text/html;charset=GB2312">
</head>
<body>
<h2>利用JavaMail来发送电子邮件 - HTML格式</h2>
<form name="SendMessage" Method="post" action="JavaMail.jsp">
<p>寄信人：<input type="text" name="From" size="30"maxlength="30"></p>
<p>收信人：<input type="text" name="To" size="30"maxlength="30"></p>
<p>主题：<input type="text" name="Subject" size="30"maxlength="30"></p>

<option value="text/plain">Text</option>
<option value="text/html">HTML</option>
</select></p>

<input type="submit" value="发送">
<input type="reset" value="重填">
</form>
</body>
</html>

JavaMail.jsp代码：
<%@ page import="javax.mail.*"%>
