邮件发送成功
用你的代码没有有测出问题，发送成功了。只测试业务逻辑，没有使用servlet方式发送

看你的qq邮箱是否支持smtp协议？
登录qq邮箱---设置--账户---POP3/IMAP/SMTP/Exchange服务---勾选POP3/SMTP服务。再试

我之前也做了一个javamail，上传都我的资源里，自己看吧，包含数据库的；

你的Debug第4行显示的是DEBUG SMTP: useEhlo true, useAuth true但是我测试显示的是DEBUG SMTP: useEhlo true, useAuth false

邮箱的smtp是开启的，换了sina、qq的邮箱服务器都不行啊——怎么看javamail的版本，我在网上下的就光是个mail.jar 和activiation.jar的名字，没有版本号

好，我试试数字邮箱
4l的朋友测试的邮件还在我邮箱里可以看见，就是说是可以发送成功的。可我自己就是发布成功
javamail是1.4ea版本的

数字邮箱也不行啊。
测试还是显示
DEBUG SMTP: useEhlo true, useAuth false

props.put("mail.smtp.auth", true);改为
props.put("mail.smtp.auth", "true");看下

你先不要用servlet，直接用main方法测一下你的后台代码。如果能通，那就是你配置的问题了。先试试

调试易
