Question

我正在尝试使用SMTP从我的网站发送电子邮件。我每次都会收到错误。我使用我的ISP smtp服务器在本地测试它，它工作得很好。现在我在网上虽然情况并非如此。我不知道我得到的错误是什么，然后它不起作用，我收到我已编入网站的错误消息。你可以在下面看到我的代码。

我尝试了几个不同的服务器而没有运气。我知道登录/密码很好，因为我验证了它。我的托管服务提供商是winhost，但我的电子邮件通过gmail。因此，我在godaddy上设置了一个允许250个继电器的帐户。

public class EmailMeController : Controller
{
    //
    // GET: /EmailMe/

    [AcceptVerbs(HttpVerbs.Get)]
    public ActionResult Index()
    {
        return View();
    }

    [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult Index(EmailModel emailModel)
    {
        if (ModelState.IsValid)
        {
            bool isOk = false;
            try
            {
                MailMessage msg = new MailMessage();
                msg.From = new MailAddress("no-reply@openskymedia.com", "Website Contact Form");
                msg.To.Add("admin@openskymedia.com");
                msg.Subject = emailModel.Subject;
                string body = "Name: " + emailModel.Name + "\n"
                            + "Email: " + emailModel.EmailAddress + "\n"
                            + "Website: " + emailModel.WebSite + "\n"
                            + "Phone: " + emailModel.Phone + "\n\n"
                            + emailModel.Message;

                msg.Body = body;
                msg.IsBodyHtml = false;

                SmtpClient smtp = new SmtpClient("smtp.secureserver.net", 80);
                NetworkCredential Credentials = new NetworkCredential("postmaster2@domain.com", "password");
                smtp.Credentials = Credentials;

                smtp.Send(msg);

                msg.Dispose();

                isOk = true;

                MessageModel rcpt = new MessageModel();
                rcpt.Title = "Thank You";
                rcpt.Content = "Your email has been sent.";
                return View("Message", rcpt);
            }
            catch (Exception ex)
            {
            }

            // If we are here...something kicked us into the exception.
            //
            MessageModel err = new MessageModel();
            err.Title = "Email Error";
            err.Content = "The website is having an issue with sending email at this time. Sorry for the inconvenience. My email address is provided on the about page.";
            return View("Message", err);
        }
        else
        {
            return View();
        }
    }

Answer 1

您正在吞咽您的例外情况。在这个catch块中：

61.                catch (Exception ex)
62.                {
63.                }

只写出错误：

Response.Write( ex.ToString() )

此外，请务必遍历任何内部异常，例如：

while( ex != null ){
Response.Write( "<HR>" + ex.ToString() );
ex = ex.InnerException;
}

Answer 2

问题的解决方案就是这样。我最终使用winhosts SMTP。我托管的电子邮件托管在谷歌上。我无法发送到与我的托管公司属于同一域的电子邮件地址，因为它首先查找了该电子邮件地址。当它没有找到它时，它会出错。相反，我必须将电子邮件发送到我的Gmail帐户，然后根据回复地址和电子邮件中的某些文本转发到我的openskymedia地址。这有点令人费解，但它确实奏效了。下面的代码能够让我从表单发送电子邮件并且运行得非常好。

public ActionResult Index(EmailModel emailModel)
        {
            if (ModelState.IsValid)
            {
                bool isOk = false;
                try
                {
                    MailMessage msg = new MailMessage();
                    msg.From = new MailAddress("no-reply@openskymedia.com", "Website Contact Form");
                    msg.To.Add("jasshultz@gmail.com");
                    msg.Subject = emailModel.Subject;
                    string body = "Name: " + emailModel.Name + "\n"
                                + "Email: " + emailModel.EmailAddress + "\n"
                                + "Website: " + emailModel.WebSite + "\n"
                                + "Phone: " + emailModel.Phone + "\n\n"
                                + emailModel.Message;

                    msg.Body = body;
                    msg.IsBodyHtml = false;

                    SmtpClient smtp = new SmtpClient("your.server.com");
                    NetworkCredential Credentials = new NetworkCredential("email@domain.com", "password");
                    smtp.Credentials = Credentials;

                    smtp.Send(msg);

                    msg.Dispose();

                    isOk = true;

                    MessageModel rcpt = new MessageModel();
                    rcpt.Title = "Thank You";
                    rcpt.Content = "Your email has been sent.";
                    return View("Message", rcpt);
                }
                catch (Exception ex)
                {
                    //while (ex != null)
                    //{
                    //    Response.Write("<HR>" + ex.ToString());
                    //    ex = ex.InnerException;
                    //}

                }

                // If we are here...something kicked us into the exception.
                //
                MessageModel err = new MessageModel();
                err.Title = "Email Error";
                err.Content = "The website is having an issue with sending email at this time. Sorry for the inconvenience. My email address is provided on the about page.";
                return View("Message", err);
            }
            else
            {
                return View();
            }
        }

除了做Dave告诉你的事情，你是否尝试使用本地iis作为smtp服务器？您可以在web.net部分的web.config文件中执行此操作。

<system.net>
    <mailSettings>
        <smtp from="username@domain">
            <network host="localhost" />
        </smtp>
    </mailSettings>
</system.net>
