Question

我正在尝试使用下面的代码和配置从ASP.Net通过GMail发送电子邮件。不幸的是，它似乎没有工作，它也没有抛出错误信息。服务器日志或邮件IIS邮件文件夹中没有任何内容，我甚至检查了来自地址的垃圾箱，看看邮件是否在那里结束。任何帮助都会非常感激。

C＃部分

    public void SendFeedback()
    {
        string emailFrom = this.Email.Text;

        MailMessage message = new MailMessage();
        // here is an important part:
        message.From = new MailAddress(emailFrom, "Mailer");
        // it's superfluous part here since from address is defined in .config file
        // in my example. But since you don't use .config file, you will need it.
        message.Subject = "www.gumpshen.com - Website Query";
        message.IsBodyHtml = true;
        message.Body = string.Format(" Name = {0}, Phone = {1}", Name.Text, Phone.Text);
        message.Body += Environment.NewLine;
        message.Body += Environment.NewLine;
        message.Body += ProjectDetails.Text; ;

        var client = new SmtpClient();

        try
        {
            client.Send(message);

这是配置部分：

<system.net>
  <mailSettings>
    <smtp from="myEmail@gmail.com" deliveryMethod="Network" >
      <network host="smtp.gmail.com" port="587" 
        userName="myEmail@gmail.com" password="myPassword"/>
    </smtp>
  </mailSettings>
</system.net>

您需要client.EnableSsl=true;

检查此网站的代码：Email via Gmail

以下是如何使用您的Google帐户从ASP.NET页面发送HTML电子邮件的示例。（此设置可以轻松用于通过需要身份验证的任何其他SMTP服务器发送邮件）。注意：代码段假设您在页面上有一个名为lblMsg的Label组件将显示发送电子邮件的用户的成功/失败消息。（但这很容易改变）。

   SmtpClient client = new SmtpClient();
   client.DeliveryMethod = SmtpDeliveryMethod.Network;
   client.EnableSsl = true;
   client.Host = "smtp.gmail.com";
   client.Port = 587;

   // setup Smtp authentication
   System.Net.NetworkCredential credentials = 
       new System.Net.NetworkCredential("your_account@gmail.com", "yourpassword");
   client.UseDefaultCredentials = false;
   client.Credentials = credentials;                

   MailMessage msg = new MailMessage();
   msg.From = new MailAddress("your_account@gmail.com");
   msg.To.Add(new MailAddress("destination_address@someserver.com"));

   msg.Subject = "This is a test Email subject";
   msg.IsBodyHtml = true;
   msg.Body = string.Format("<html><head></head><body><b>Test HTML Email</b></body>");

   try
   {
       client.Send(msg);
       lblMsg.Text = "Your message has been successfully sent.";
   }
   catch (Exception ex)
   {
       lblMsg.ForeColor = Color.Red;
       lblMsg.Text = "Error occured while sending your message." + ex.Message;
   }
