我一直在使用ASP.NET MVC的网站上工作,您可以直接向特定的电子邮件地址发送电子邮件。它工作正常,电子邮件发送没有问题。直到我主持它。我一直收到这个错误:

  

尝试以其禁止的方式访问套接字   访问权限65.55.176.126:587

执行期间生成了未处理的异常   当前的网络请求。有关的来源和位置的信息   可以使用下面的异常堆栈跟踪来识别异常。

我不知道为什么它在localhost上工作但在托管网站上没有。有人请帮帮我。我是新手。先感谢您。这是我的控制器:

    public ActionResult Index()
    {
        return View();
    }

    [HttpPost]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Index(EmailFormModel model, IEnumerable<HttpPostedFileBase> files)
    {
        if (ModelState.IsValid)
        { 
            List<string> paths = new List<string>();

            foreach (var file in files)
            {
                if (file.ContentLength > 0)
                {
                    var fileName = Path.GetFileName(file.FileName);
                    var path = Path.Combine(System.Web.HttpContext.Current.Server.MapPath("~/App_Data/uploads"), fileName);
                    file.SaveAs(path);
                    paths.Add(path);

                    string fileName = fileInfo.Name;
                    message.Attachments.Add(new Attachment(memoryStream, fileName));
                }

                //Rest of business logic here

                    message.Body = string.Format(body, model.FromName, model.FromEmail, model.FromSubject, model.Message, model.Desc);
                    message.IsBodyHtml = true;
                    using (var smtp = new SmtpClient())

                        ModelState.Clear();

            } return View(model);

        }

我认为它可能是您正在使用的端口。根据msdn,如果你的端口高于465,你需要使用不同的SMTP库(而不是StmpClient)。
