Question

我最近已切换到ASP.NET MVC。当人们注册我的网站时，我想发送电子邮件确认。

因此，我默认取消注释ASP.NET MVC默认的代码，并在web.config中添加配置，但这不起作用，我一直有这个错误：

SMTP服务器需要安全连接，或者客户端未经过身份验证。服务器响应为：5.5.1需要身份验证。

我创建了一个asp.net webforms，并尝试从该项目发送电子邮件，并且工作正常。所以我复制了我在页面加载时使用的代码，用于在webforms中发送电子邮件，并将其放入帐户控制器的注册操作中，但我又遇到了错误。

我真的不明白为什么我在ASP.NET MVC中遇到这个错误，但完全相同的代码在webforms中工作正常。

这是ASP.NET MVC注册操作中的代码：

public async Task<ActionResult> Register(RegisterViewModel model)
{
        if (ModelState.IsValid)
        {
            var user = new ApplicationUser { UserName = model.Email, Email = model.Email, BirthDate=model.BirthDate };

            var result = await UserManager.CreateAsync(user, model.Password);
            if (result.Succeeded)
            {
                await SignInManager.SignInAsync(user, isPersistent:false, rememberBrowser:false);

                // For more information on how to enable account confirmation and password reset please visit http://go.microsoft.com/fwlink/?LinkID=320771
                // Send an email with this link
                //string code = await UserManager.GenerateEmailConfirmationTokenAsync(user.Id);
                //var callbackUrl = Url.Action("ConfirmEmail", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
                //await UserManager.SendEmailAsync(user.Id, "Confirm your account", "Please confirm your account by clicking <a href=\"" + callbackUrl + "\">here</a>");

                //create the mail message 
                MailMessage mail = new MailMessage();

                //set the addresses 
                mail.From = new MailAddress("info@wwwebco.com"); //IMPORTANT: This must be same as your smtp authentication address.
                mail.To.Add(user.Id);

                //set the content 
                mail.Subject = "This is an email";
                mail.Body = "This is from system.net.mail using C sharp with smtp authentication.";
                //send the message 
                SmtpClient smtp = new SmtpClient("mail.wwwebco.com");

                //IMPORANT:  Your smtp login email MUST be same as your FROM address. 
                NetworkCredential Credentials = new NetworkCredential("info@wwwebco.com", "MyPassWord");
                smtp.Credentials = Credentials;
                await smtp.SendMailAsync(mail);

                return RedirectToAction("Index", "Home");
            }
            AddErrors(result);
        }

        // If we got this far, something failed, redisplay form
        return View(model);
    }

我在asp.net webforms应用程序中的代码和工作正常是：

protected void Page_Load(object sender, EventArgs e)
{
    //create the mail message 
    MailMessage mail = new MailMessage();

    //set the addresses 
    mail.From = new MailAddress("info@wwwebco.com"); //IMPORTANT: This must be same as your smtp authentication address.
    mail.To.Add("armanhafezi@gmail.com");

    //set the content 
    mail.Subject = "This is an email";
    mail.Body = "This is from system.net.mail using C sharp with smtp authentication.";
    //send the message 
    SmtpClient smtp = new SmtpClient("mail.wwwebco.com");

    //IMPORANT:  Your smtp login email MUST be same as your FROM address. 
    NetworkCredential Credentials = new NetworkCredential("info@wwwebco.com", "MyPassWord");
    smtp.Credentials = Credentials;
    smtp.Send(mail); 

}

我真的很困惑这个问题。请帮忙！

谢谢。

更新：

您为什么使用user.Id而非model.Email？

如果您有任何空白或遗漏的详细信息，这可能会导致错误？

<强>原始

您应该将mail.From更改为mail.Sender。

您是否将ASP.NET Web窗体和MVC加载到同一主机环境中？可以阻止端口25，还是要求通过HTTPS发送SMTP？

对于HTTPS，您需要更改端口号，通常是端口465，但可能会有所不同，具体取决于您的邮件发件人。

如果您的SMTP服务器有限制，请尝试使用SendGrid，该帐户有免费帐户。

电子邮件不会发送到mvc但在asp.net webform中工作
