以下代码无法向客户发送电子邮件，并且不会引发任何异常。该代码没有发送任何电子邮件或异常，但已执行。我对asp.net一无所知。有人能帮我解决这个问题

代码：

try
{
    String userName = "ramesh";
    String passWord = "123456";
    String sendr = "ramesh@gmail.com";
    String recer = "customer@yahoo.com";
    String subject = "Comformation ";
    String body = "Dear Customer";

    MailMessage msgMail = new MailMessage(sendr, recer, subject, body);

    int PortNumber = 25;
    SmtpClient smtp = new SmtpClient("smtp.test.com", PortNumber);
    msgMail.IsBodyHtml = true;                                     
    smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
    smtp.Credentials = new System.Net.NetworkCredential(userName, passWord);

    smtp.Send(msgMail);

    MsgLP.Text = "Emailed to Customer..";
    LogInLink.Visible = true;
}
catch (Exception ex){
    AuditLog.LogError("ErrorE-mail " + ex.Message);
}
您必须设置
smtp.EnableSsl=true
并使用端口号
587
。您的最终代码如下：

try
{
String userName = "ramesh";
String passWord = "123456";
String sendr = "ramesh@gmail.com";
String recer = "customer@yahoo.com";
String subject = "Comformation ";
String body = "Dear Customer";

MailMessage msgMail = new MailMessage(sendr, recer, subject, body);

int PortNumber = 587; //change port number to 587
SmtpClient smtp = new SmtpClient("smtp.gmail.com", PortNumber); //change from test to gmail
smtp.EnableSsl = true; //set EnableSsl to true
msgMail.IsBodyHtml = true;                                     
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.Credentials = new System.Net.NetworkCredential(userName, passWord);
smtp.Send(msgMail);
MsgLP.Text = "Emailed to Customer..";
LogInLink.Visible = true;
}
catch (Exception ex){
AuditLog.LogError("ErrorE-mail " + ex.Message);
}
我用我的凭据测试了此代码，它工作正常。

您是否查看过垃圾邮件？邮件服务器上有任何安全设置吗？你能告诉我如何检查邮件服务器上的垃圾邮件安全设置吗？如果邮件服务器没有发送，你怎么知道它没有发送邮件？我建议您的代码可以正常工作，但途中的smtp服务器无法发送电子邮件。我的意思是在您发送电子邮件的yahoo mail的垃圾邮件文件夹中。您是否使用自己的邮件服务器或第三方。如果您在办公室，您可以从网络部门确认。@Ben Robinson，我将在哪里配置SmtpClient服务器以及如何检查服务器状态您在垃圾邮件中查看了吗？邮件服务器上有任何安全设置吗？你能告诉我如何检查邮件服务器上的垃圾邮件安全设置吗？如果邮件服务器没有发送，你怎么知道它没有发送邮件？我建议你的代码可以正常工作，但一路上smtp服务器并没有发送电子邮件。我的意思是在你发送emai的雅虎邮件的垃圾邮件文件夹中
