不能从服务器发送邮件?

We built an ASP.NET app that we deployed on the client's server, using their SMTP server.

我们建立了一个ASP。我们部署在客户端服务器上的NET应用程序，使用他们的SMTP服务器。

I'm trying to have Elmah send error emails using the ErrorEmailModule. This uses the SMTP settings as configured in the web.config, but somehow sending emails is not working (nothing is being sent).

我想让Elmah使用ErrorEmailModule发送错误邮件。这将使用web中配置的SMTP设置。配置，但是发送电子邮件是不工作的(什么都没有发送)。

The SMTP settings are configured like this:

SMTP设置是这样配置的:

  <system.net>
    <mailSettings>
      <smtp from="[e-mail]">
        <network host="xxxxxxx.management.local" port="25" enableSsl="true" defaultCredentials="true"/>
      </smtp>
    </mailSettings>
  </system.net>

To test if this is a problem with Elmah or with the config I created a little test application that uses the same setting and tries to send an email:

为了测试这是否是Elmah的问题，或者配置我创建了一个小测试应用程序，使用相同的设置并尝试发送电子邮件:

string from = "[e-mail]";
string to = ConfigurationManager.AppSettings["ErrorReportingEmail"];
var message = new MailMessage(from, to, "Test", "Test");
var smtpClient = new SmtpClient();

smtpClient.Send(message);

This doesn't work either. SmtpClient doesn't throw an error, it just acts like it sent an email, but I'm not receiving anything.

这并不奏效。SmtpClient不会抛出错误，它只是像发送邮件一样，但我没有收到任何东西。

I then tried sending an email using 2 different email testing tools, called MailTester and MultiMail, I entered the same SMTP settings, and they can send emails just fine.

然后我试着用两种不同的电子邮件测试工具——MailTester和MultiMail——发送电子邮件，我输入了相同的SMTP设置，他们可以发送电子邮件。

So my question is: why can I send emails from these mail tester apps but not from my ASP.NET app?

所以我的问题是:为什么我可以从这些邮件测试应用程序中发送电子邮件，而不是从ASP中发送。网络应用程序?

try this set deliveryMethod = network.

试试这个set deliveryMethod = network。

   <system.net>
    <mailSettings>
      <smtp from="[e-mail]" deliveryMethod="Network">
        <network host="xxxxxxx.management.local" port="25" enableSsl="true" defaultCredentials="true"/>
      </smtp>
    </mailSettings>
  </system.net>
