用配置文件的MailSettings SMTP认证 [英] SMTP Authentication with config file's MailSettings

问题描述

我存储我MailSettings在一个web.config，但是当我发送邮件，我的SMTP服务器报告回，我需要使用身份验证。我有在配置文件中我的用户名/密码，但它仍然会失败。

I'm storing my MailSettings in a web.config, however when I send the message, my SMTP server reports back that I need to use authentication. I've got my username/password in the config file, but it still fails.

它的工作原理，如果我这样做，但它似乎是一个额外的步骤。难道不应该只是把它从配置文件并自动使用验证？

It works if I do the following, but it seems like an extra step. Shouldn't it just take it from the config file and use authentication automatically?

System.Configuration.Configuration config = WebConfigurationManager.OpenWebConfiguration(HttpContext.Current.Request.ApplicationPath);
MailSettingsSectionGroup settings = (MailSettingsSectionGroup) config.GetSectionGroup("system.net/mailSettings");

SmtpClient client = new SmtpClient();
client.Credentials = new NetworkCredential(settings.Smtp.Network.UserName, settings.Smtp.Network.Password);

Web.config文件

Web.config

<system.net>
    <mailSettings>
      <smtp from="[e-mail]" deliveryMethod="Network">
        <network host="mail.xyz.com" defaultCredentials="true" userName="me@xyzcom" password="abc123" />
      </smtp>
    </mailSettings>
  </system.net>

在超出存储分配糊涂我们很长一段时间，现在我们忽略它。这是使用SMTP验证，这似乎是很重要的。

The "Exceeded storage allocation" confused us for quite awhile, we now ignore it. It's the "use smtp authentication" that seems to be important.

推荐答案

在codeD方法和 web.config中只有的做法是，后者有 =的DefaultCredentials真实集。那是$ P $被用来进行身份验证，这种做法pventing用户名和密码。我认为这个问题会通过设置为假来解决（或者完全删除，因为假是默认值）。

The difference between the coded approach and the web.config only approach is that the latter has defaultCredentials="true" set. That is preventing the username and password from being used to authenticate, with that approach. I think the problem would be solved by setting that to "false" (or removing it completely, because "false" is the default).
