下载了一大堆发送emial的源代码程序，没有一个成功发送了邮件。有一个特别不明白的地方：为什么没有地方让我输入登录用户名和密码？用户名可以认为隐含，但密码呢？还有服务器连接方面也总不正确。（有一个在单步方式可以连上，一执行就连不上）请教各位高手！

前一个问题：“有关发送email的源代码问题，请教各位高手！”

解决了在两个地方一起加分！

Star CCM+中衍生零部件下的阈值应用与区域内删除目标网格同样的在绘制网格结束后，有时出现负体积网格或质量差的网格，为了节约时间成本，可能会选择将负体积的网格或质量差的网格删除。弹出相应的窗口，在窗口中选择相应的区域①，选择标量函数②（此处以网格体积变化为例），选择模型③，设置阈值④，选择No Dispalyer，会根据需求选择显示，最后点击Create⑥完成创建。此处以温度为例，若出现温度异常点，首先在①栏中勾选Function，然后在下面点击⑤Select，在弹出的Function窗口中选择温度场函数，再点击④Identify，查找温度异常网格数量。阅读详情

发送的时候如果服务器不需要身份认证，也可以不要密码。
你还是先看一下SMTP协议再编程序吧。

你可以用
c:\>telnet your_smtp_server 25

来学习如何用SMTP与服务器通信。
