发送给收件人，同时在发件人列表中列出其他人 [英] Send to a recipient, while listing others in the sent-to list

问题描述

我想向一个人发送电子邮件，但发送给列表显示多个人。 （我不希望其他人收到电子邮件）。

I'd like to send an email to a single person, yet have the "sent to" list display a number of people. (I don't want those other people to receive the email).

许多文章（此处和在此）建议为smtp地址和mime地址指定不同的值是完全合法的。

A number of articles (here and here) suggest it's perfectly legal to specify different values for smtp address and mime addresses.

我正在使用MailKit，这就是事实我到目前为止：

I'm using MailKit and this is what I have so far:

var message = new MimeMessage();
message.From.Add(new MailboxAddress("MeetingOfficeA", "[e-mail]"));
message.To.Add(new MailboxAddress("Fidel Perez-Smith", "[e-mail]"));

message.Headers.Add("To", "[e-mail]"); //this line actually sends the email to John Doe, which I don't want

message.Subject = "Testing";
message.Body = new TextPart ("plain") { Text = @"Testing 123" };

MailKit.Net.Smtp.SmtpClient client = new MailKit.Net.Smtp.SmtpClient();
client.Connect("smtpserver.office.com");
client.Send(message);

我是否可以添加一些内容，因此只有Fidel可以接收该电子邮件，但看起来已发送至

Is there something I can add so only Fidel receives the email, yet it looks like it was sent to multiple people?

（链接1中的问题类似，但主要讨论发件人地址。我认为我的问题不应标记为重复，因为它与到地址，将使其他用户更容易找到它。毕竟，当我研究特定问题时，花了一段时间才找到另一个链接）。

(The question in link 1 is similar, but mainly discusses the 'from' addresses. I think my question should not be marked as duplicate because it relates to the 'to addresses' and will make it easier for other users to find. After all, it took a while to find that other link when I was researching my particular issue).

推荐答案

下面的代码片段将使该消息既发送给Fidel Perez-Smith，又发送给John Doe，看起来像，但实际上，它只是发送给Fidel Perez-Smith：

The following code snippet will make it look like the message was sent to both Fidel Perez-Smith and John Doe, but in reality, it will only be sent to Fidel Perez-Smith:

var message = new MimeMessage ();
message.From.Add (new MailboxAddress ("MeetingOfficeA", "[e-mail]"));
message.To.Add (new MailboxAddress ("Fidel Perez-Smith", "[e-mail]"));
message.To.Add (new MailboxAddress ("John Doe", "[e-mail]");
message.Subject = "Testing";
message.Body = new TextPart ("plain") { Text = @"Testing 123" };

using (var client = new SmtpClient ()) {
    client.Connect ("smtpserver.office.com");
    client.Send (message, new MailboxAddress ("MeetingOfficeA", "[e-mail]"), new [] { new MailboxAddress ("Fidel Perez-Smith", "[e-mail]") });
    client.Disconnect (true);
}
