Answer 1

//包含用户名和密码  
client.Credentials=new System.Net.NetworkCredential(UserName,Password);  //发件人身份验证,否则163   发不了  
client.Credentials=new System.Net.NetworkCredential(strFrom,Password);  -------------------------------------
你自己查一下自己的代码吧。
.Net只有越做越好，不会是越做越差的。

Answer 2

fail   邮箱不可用。 服务器响应为: Óû§±»Ëø¶¨ 
 无语了。呵呵。
