无法从asp.net发送电子邮件

Question

它适用于特定的电子邮件地址，但其余电子邮件无效。.出现以下错误：

Server Error in '/RealTimeArsenicDataVisualizer' Application.
Mailbox name not allowed. The server response was: From address not verified - see http://help.yahoo.com/l/us/yahoo/mail/original/manage/sendfrom-07.html 

我的代码：

 System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient("smtp.mail.yahoo.co.in", 587);

        client.UseDefaultCredentials = false;
     client.Credentials = new System.Net.NetworkCredential(emailid, password);

            client.Port = 587;

            client.Host = "smtp.mail.yahoo.co.in";

            client.EnableSsl = false;

            object userstate = msg;

            client.Send(msg);

将代码更改为以下代码：

client.Port = 465;

client.Host = " smtp.mail.yahoo.com";
client.EnableSsl = true;
