Question

我正在尝试在系统处理完付款后向自己发送电子邮件通知。我使用以下代码：

public Exception SendEmail(string subject, string body)
    try
    {
        var fromAddress = new MailAddress(Setting.Get("smtp_from"), Setting.Get("smtp_from_name"));
        var toAddress = new MailAddress(Setting.Get("smtp_to"), Setting.Get("smtp_to"));

        var smtp = new SmtpClient
        {
            Host = Setting.Get("smtp_host"),
            Port = Int32.Parse(Setting.Get("smtp_port")),
            EnableSsl = true,
            DeliveryMethod = SmtpDeliveryMethod.Network,
            Credentials = new NetworkCredential(fromAddress.Address, Setting.Get("smtp_password")),
            Timeout = Int32.Parse(Setting.Get("smtp_timeout"))
        };
        using (var message = new MailMessage(fromAddress, toAddress)
        {
            Subject = subject,
            Body = body
        })
        {
            smtp.Send(message);
        }

        return null; //All went well
    }
    catch (Exception ex)
    {
        return ex;
    }
}

没有什么特别的，只有谷歌发现的基本代码。此代码可以完美地使用以下消息和主题：

Subject: [SUCCESS] Donation processed successfully
Message: This is a test.

但是，当消息更改为：

Donation received and processed successfully! No further action is required.
Donor: John Doe
Donation amount: 4,00 EUR
Email: fake@user.com
Mandrill API Response: Sent

我的收件箱中没有显示任何内容。它确实显示在发送电子邮件的帐户的已发送项目中。我检查了一切，垃圾邮件，捶打，但它没有到达。

之前有没有遇到过这个？有谁知道如何解决这个问题？

Answer 1

这对我很有用：

 public static void SendEmail(string emailbody)
    {
      MailMessage mailMessage = new MailMessage("incoming email address", "receiver email address");
      mailMessage.Body = emailbody;
      mailMessage.Subject = "Feedback";

      SmtpClient smtpClient = new SmtpClient("relay-hosting.secureserver.net", 25);
      smtpClient.EnableSsl = false;
      smtpClient.Send(mailMessage);
    }

希望这有帮助

Answer 2

好的，我发现了问题。

看看这个：

using (var message = new MailMessage(fromAddress, toAddress)
{
    Subject = subject,
    Body = body
})
{
    smtp.Send(message);
}

using语句在调用.Send（message）方法之前处理MailMessage，并且由于某种原因，这不会产生异常。 facepalms

Gmail未收到某些邮件，会显示在已发送的文件夹中
