     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);

將您的代碼更改爲以下代碼：

client.Port = 465; 

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