Question

我尝试使用以下代码通过我的asp.net mvc应用程序发送电子邮件：

public ActionResult ResetPassword()
    {
        if (Session["id"] == null)
        {
            return RedirectToAction("Login", "Home");
        }
        bool status = false;

        B4URepository dalObj = new B4URepository();
        var customer = dalObj.GetCustomerDetails(Convert.ToInt32(Session["id"]));
        string email = customer.EmailId;
        string name = customer.Name;

        MailMessage mailMessage = new MailMessage();
        mailMessage.To.Add(new MailAddress(email, name));
        mailMessage.From = new MailAddress("sender-outlook-email");
        //mailMessage.Sender = new MailAddress("sender-outlook-email", "sender-name");
        mailMessage.Subject = "<h3>Password reset</h3>";
        mailMessage.Body = "Hello";
        mailMessage.IsBodyHtml = true;
        mailMessage.Priority = MailPriority.High;

        SmtpClient smtp = new SmtpClient();

        try
        {
            smtp.Send(mailMessage);
            status = true;
        }

        catch (Exception)
        {
            status = false;
        }
        if (status)
            return View("Success");
        else
            return View("Error");
    }

以及Web.config中的以下设置：

<system.net>
<mailSettings>
  <smtp from="sender-outlook-email">
    <network host="smtp-mail.outlook.com"
             port="587"
             userName="sender-outlook-email"
             password="sender-password"
             enableSsl="true"/>
  </smtp>
</mailSettings>
<!--<mailSettings>
  <smtp deliveryMethod="SpecifiedPickupDirectory">
    <specifiedPickupDirectory pickupDirectoryLocation="Z:\MailDump"/>
  </smtp>
</mailSettings>-->

使用评论代码，即邮件设置，我检查了电子邮件是否至少成功创建并发现它已创建并存储在指定目录中。

但是在尝试使用上面的代码发送邮件时，它在“smtp.Send（mailMessage）”行上给出了一个例外：

Answer 1

如果您使用的是其他凭据（登录凭据），则需要指定client name和port number，然后将UseDefaultCredentials设置为false

SmtpClient client = new SmtpClient("smtp-mail.outlook.com");
client.Port = 587;
client.UseDefaultCredentials = false;

这应该有用。

使用来自asp.net mvc应用程序的outlook smtp发送电子邮件
