1 用Apache Commons Email简化邮件发送
http://www.blogjava.net/fastunit/archive/2008/01/25/177799.html
我测试时是用的是：新浪的邮箱:smtp.sina.com也是可以的
如下设置:

Exception: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection
参考文章:http://zhidao.baidu.com/question/227409027.html
解答: 配置JavaMail的Properties时，不要指定mail.smtp.socketFactory.class,因为TLS使用的是普通的Socket。然后指定属性mail.smtp.starttls.enable为true.
介绍

Commons Email封装了javamail，使用非常简单。
功能：简单文本邮件、带附件的邮件、HTML格式的邮件
官方首页：http://commons.apache.org/email/，目前最新版本是1.2
官方示例：http://commons.apache.org/email/userguide.html

工程环境:XP+Myeclipse6.5+JDK1.6
一实现功能
1 封装了常用的四种发送Email的方法(文本,html,img,file),用户只要调用一个工厂类传递相应的邮件的属性如from, to,cc, subject,text,或者是消息对象
2 解决了发送邮件附件中的中文筹码问题
3 支持链式风格
4 可以混合发送多种消息(text,html,img,file)
二工程图片

或者你也可以这样,使用打包好的jar:email.commons.util.jar

,见附件
三调用说明
1 发送文本消息
//默认空构造为发送文本类型
//默认空构造为发送文本类型
MailMessageFactory mms = new MailMessageFactory();
mms.setSubject("使用Apache Commons Email 组件发送").setText("发送普通文本消息").send();

2 发送含有附件的消息

MailMessageFactory mms = new MailMessageFactory(SendMailType.FILE);
mms.setSubject("使用Apache Commons Email 组件发送文本及附件消息").setText("天涯海角")
.setEmailAttachment("美女.jpg","美女图片","c:\\4.jpg").send();

3 发送Html格式消息

MailMessageFactory mms = new MailMessageFactory(SendMailType.HTML);
String html = "<html><head><meta http-equiv='content-type' content='text/html; charset=GBK'>"
+ "</head><body><h1>使用Apache Commons Email发送的邮件</h1><img src=\"cid:img0\"><br><img src=\"cid:img1\"></body></html>";
mms.setSubject("使用Apache Commons Email 网页格式加入图片")
.setEmailAttachment("美女.jpg","美女图片","c:\\4.jpg")
.setEmailHtmlImgAttachment("美女2.jpg","美女图片2","img0","c:\\5.jpg")
.setEmailHtmlImgUrl("apache.jpg",null, "img1","http://www.apache.org/images/asf_logo_wide.gif")
.setHtmlText(html)
.send();

四代码如下
