在IIS7中使用我的SMTP服务器发送电子邮件时允许错误。

I just recently bought my own server with IIS7, and I'm trying to set up SMTP so that I can send an e-mail from my website.

我最近刚用IIS7购买了自己的服务器，我正在尝试设置SMTP，以便我可以从我的网站发送电子邮件。

Here's my smtp settings:

这是我的smtp设置:

Here is my code that sends the e-mail:

这是我的代码发送电子邮件:

private static void SendEmail(IEnumerable<MailAddress> to,
    IEnumerable<MailAddress> bcc, MailAddress from,
    string subject, string bodyHtml)
    {
        var mail = new MailMessage { From = from, Subject = subject,
            Body = bodyHtml, IsBodyHtml = true };

        foreach (var address in to)
        {
            mail.To.Add(address);
        }

        foreach (var address in bcc)
        {
            mail.Bcc.Add(address);
        }

        try
        {
            string server = ConfigurationManager.AppSettings["SMTPServer"];
            int port = Int32.Parse(ConfigurationManager.AppSettings["SMTPPort"]);

            var smtp = new SmtpClient
                           {
                               Host = server,
                               Port = port
                           };

            smtp.Send(mail);
        }
        catch (Exception err)
        {
        }
    }

And my config settings:

我的配置设置:

<add key="SMTPServer" value="localhost" />
<add key="SMTPPort" value="25" />

I get an error at smtp.Send(mail); that says:

我在smtp.Send(邮件)中出错;说:

Bad sequence of commands. The server response was: This mail server requires authentication when attempting to send to a non-local e-mail address. Please check your mail client settings or contact your administrator to verify that the domain or address is defined for this server.

命令的次序错误。服务器响应是:当试图发送到非本地的电子邮件地址时，该邮件服务器需要身份验证。请检查您的邮件客户端设置或联系您的管理员，以确认该服务器的域或地址。

Well, I have no authentication requirements on my smtp server, it says so in my settings in the screenshot.

我在我的smtp服务器上没有认证要求，在我的屏幕截图的设置中是这样说的。

I looked around, and other people had this problem if they were sending the e-mail from a different e-mail specified in their settings, but I'm sending mine from [e-mail]. I am sending it to an @gmail.com account though, so it is sending to a non-local e-mail address.

我环顾四周，如果他们在设置中使用不同的电子邮件发送电子邮件，其他人也有这个问题，但是我从[e-mail]发送我的邮件。我将它发送到@gmail.com帐户，所以它将发送到一个非本地的电子邮件地址。

What am I doing wrong here?

我在这里做错了什么?

I wanted to add the answer to this for others searching

我想为其他人的搜索添加答案。

Make sure SMTP is up and running and no errors are being thrown. Here is a reference that might help.

确保SMTP已启动并运行，并没有抛出错误。这里有一个可能会有所帮助的参考。
