Gmail郵件被拒絕

Question

我試圖使用「System.Net.Mail.MailMessage」從ASP.net項目發送電子郵件。我需要將約30個聯繫人添加到「收件人」或「密件抄送」列表。

它適用於少數收件人，但數量增加;

的Gmail給錯誤：

"Message rejected. See http://support.google.com/mail/bin/answer.py?answer=69585 for more information."

阻擋了我的accont發送的電郵1天。

我怎樣才能讓gmail發送電子郵件給許多收件人？ 如果不是什麼替代方法？

您應該可以舒適地發送到30個地址。

我嘗試了CC列表（工作了要列出以及）與下面的測試代碼40個的電子郵件地址，

   string mailFrom = "test123@gmail.com";      
       string mailTo = "testccc@domain.com"; //One of your test emails 

       MailAddress to = new MailAddress(mailTo); 
       MailAddress from = new MailAddress(mailFrom); 

       MailMessage mail = new MailMessage(from, to); 

       mail.Subject = "Test subject"; 
       mail.Body = "Hello world!!!!"; 
       //Keep adding your emails as follows, do it in a for loop 
       mail.CC.Add("dhanuka1@domain.com"); 
       mail.CC.Add("dhanuka2@domain.com"); 
       ... 
       SmtpClient smtp = new SmtpClient(); 
       smtp.Host = "smtp.gmail.com"; 
       smtp.Port = 587; 
       smtp.UseDefaultCredentials = false; 

       smtp.Credentials = new NetworkCredential("mydev@gmail.com", "password");//Your credentials 
       smtp.EnableSsl = true; 
       Console.WriteLine("Sending email..."); 
       smtp.Send(mail); 
       Console.WriteLine("Email sent..."); 
       Console.ReadLine();
