使用ASP.NET Core“联系我们”页面 - SMTP服务器问题

I'm new to web programming and am using ASP.NET core to make a website. I'm trying to create a standard "contact me" page where the user enters in a name, email, subject and username. I'm using the MailKit library to send the emails:

我是网络编程的新手，我正在使用ASP.NET核心来创建一个网站。我正在尝试创建一个标准的“与我联系”页面，用户可以在其中输入姓名，电子邮件，主题和用户名。我正在使用MailKit库发送电子邮件：

public IActionResult SendEmail(Contact contact)
{
    var emailMessage = new MimeMessage();

    emailMessage.From.Add(new MailboxAddress(contact.Name, contact.Email));
    emailMessage.To.Add(new MailboxAddress("myname", "myemail"));
    emailMessage.Subject = contact.Subject;
    emailMessage.Body = new TextPart("plain") { Text = contact.Message };

    using (var client = new SmtpClient())
    {
        client.Connect("smtp-mail.outlook.com", 587); 
        client.Authenticate("myemail", "myemailpassword");
        client.Send(emailMessage);
        client.Disconnect(true);
    }
    return RedirectToAction("Index", "Home");
}

My issue is that whenever I send the email the SMTP server just replaces my "from" header with my SMTP account information. This seems to be the case with not just outlook, but with every major SMTP server I've tried, including gmail. Is there an SMTP server that will not have this issue, or do I need to find another way of sending the emails?

我的问题是，每当我发送电子邮件时，SMTP服务器只是用我的SMTP帐户信息替换我的“from”标题。这似乎不仅仅是outlook的情况，而是我尝试过的每个主要SMTP服务器，包括gmail。是否有SMTP服务器不会出现此问题，或者我是否需要找到另一种发送电子邮件的方式？

First of all there is a problem with your code

首先，您的代码存在问题

    public IActionResult SendEmail(Contact contact)
    {
        var emailMessage = new MimeMessage();
        emailMessage.From.Add(new MailboxAddress("myname", "mymail@mail.com"));
        emailMessage.To.Add(new MailboxAddress("myname", "mymail@mail.com"));
        emailMessage.Subject = contact.Subject;
        emailMessage.Body = new TextPart("plain") 
        { 
         Text = String.Format("This visitor:{0} with this email:{1} Send this message:{2}", 
         contact.Name, contact.Email, contact.Message) 
        };

        using (var client = new SmtpClient())
        {
            client.Connect("smtp-mail.outlook.com", 587);
            client.Authenticate("myemail", "myemailpassword");
            client.Send(emailMessage);
            client.Disconnect(true);
        }
        return RedirectToAction("Index", "Home");
    }
