温馨提示：由于发送邮件次数过多，会被官方标注，以至于邮件会放到垃圾邮箱，测试的小伙伴们注意了！
废话不多说，下面上代码：
package com.tpyin.test;
import java.util.Properties;
import org.apache.commons.mail.EmailException;
import org.apache.commons.mail.HtmlEmail;
/**
*
* @author 执草书云
*发送邮箱测试
*所需jar包
*mail.jar
*commons-email-1.1.jar
*
*注意事项：
*使用myeclipse开发在导入jar包时有可能会和Java EE 5 Libraries 的mail包冲突而抛出异常
*Exception in thread "main" java.lang.NoClassDefFoundError: com/mail/util/LineInputStream
at javax.mail.internet.MimeUtility.<clinit>(MimeUtility.java:1161)

*解决方法：本人用的myelipse10 下面就已10为例
*打开myeclipse安装目录
*E:\myeclipse10\Common\plugins\com.genuitec.eclipse.j2eedt.core_10.0.0.me201203160414\data\libraryset\EE_5，以压缩包形式打开javaee.jar，然后删除mail即可
