}

另外，我一共引了两个包：mail.jar , activation.jar

---

up

---

没有问题啊！我把你的程序执行了2次。。应该有收到吧！
我想应该是你javamail买配置好。你将mail.jar , activation.jar这两个包放到J2SDK/jre/lib/ext中去

---

你用的代码就是我以前写的，现在看来好多地方都能简单化的。

---

我是在jbuilder2005中用 这两个包我都已经引入工程了

这是提示

to hefei0603(风雨) : 你有msn吗　能告诉我下吗　　我这就是发不出去　　真是急啊！

---

25端口开了没有？
先把防火墙去了再试试

---

哪的 25端口？

---

完全没问题 谢谢你的代码

---

study

---

你关掉WIDOWS防火墙后能成功吗?

---

设置本机dns.
问题是smtp.163.com转不成ip
