发送邮件到c＃中的gmail ssl问题

Question

我尝试通过c＃发送邮件，但每次出现ssl错误。你能告诉我什么不对吗？

谢谢

SmtpClient mail = new SmtpClient();
MailMessage msg = new MailMessage("address", "address");
msg.Subject = "send data";
msg.Body = "Stuff";
mail.Credentials = new NetworkCredential("username", "pw");
mail.Host = "smtp.googlemail.com";

Attachment data = new Attachment(path1);
msg.Attachments.Add(data);
Attachment data2 = new Attachment(path2);
msg.Attachments.Add(data2);
Attachment data3 = new Attachment(path3);
msg.Attachments.Add(data3);

mail.Send(msg);

Answer 1

mail.DeliveryMethod = SmtpDeliveryMethod.Network;
mail.EnableSsl = true;
mail.Port = 587;

Answer 2

  

出现错误：服务器答案：5.3.2抱歉，在试用期内，您不能使用SMTP服务{mp018}

从这个错误我假设你刚刚注册了谷歌帐户，谷歌不允许你使用它的smtp服务，直到它的试用期结束。找出试用期有多长，并尝试何时结束

Answer 3

尝试将mail.EnableSsl设为true。
