How do I send an email to an Exchange Distribution list using c#
提问by Calanus
I need to send an email to an Exchange distribution list called "DL-IT" using c#.
我需要使用 c# 向名为“DL-IT”的 Exchange 分发列表发送电子邮件。
Does anyone know how to achieve this?
有谁知道如何实现这一目标？

The simplest way would be to find the actual email address of the DL, and use that in your "To:" field. Exchange distribution lists actually have their own email addresses, so this should work fine.
最简单的方法是找到 DL 的实际电子邮件地址，并在“收件人：”字段中使用该地址。Exchange 通讯组列表实际上有自己的电子邮件地址，所以这应该可以正常工作。

Exchange server runs SMTP so one can use the SmtpClientto send an email.
Exchange 服务器运行 SMTP，因此可以使用SmtpClient发送电子邮件。
One can lookup the SMTP address of the distribution list (manually) and use that as the "to" address on the MailMessageconstructor. The constructor call will fail if you just pass in the name of the distribution list as it doesn't looklike a realemail address.
可以（手动）查找通讯组列表的 SMTP 地址，并将其用作MailMessage构造函数上的“收件人”地址。如果您只是传入分发列表的名称，则构造函数调用将失败，因为它看起来不像真正的电子邮件地址。
public void Send(string server, string from, string to)
{
// Client to Exchange server
SmtpClient client = new SmtpClient(server);
// Message
MailMessage message = new MailMessage(from, to);
message.Body = "This is a test e-mail message sent by an application. ";
message.Subject = "test message 1";
// Credentials are necessary if the server requires the client
// to authenticate before it will send e-mail on the client's behalf.
client.Credentials = CredentialCache.DefaultNetworkCredentials;
// Send
client.Send(message);
}

Basically you need to combine two solutions above.
基本上你需要结合上面的两个解决方案。
Using code snippet from Scott solution - you should send to [email protected].
使用 Scott 解决方案中的代码片段 - 您应该发送到[email protected].
But exchange name alias is not always the same as group e-mail, so
但是交换名称别名并不总是与群组电子邮件相同，因此
- you may open an empty e-mail in Outlook with
DL-ITinTofield - double-click the
DL-ITinTofield - copy value from
Alias Namefield and add@mycompany.com.
- 您可以在 Outlook 中使用
DL-ITinTo字段打开一封空电子邮件 - 双击
DL-IT输入To字段 - 从
Alias Name字段复制值并添加@mycompany.com.

The above answers are fine, just be aware that if one of the members of the of the distribution list is not a valid address, the SMTP server may reject the entire Email message as being undeliverable.
上面的答案很好，请注意，如果通讯组列表的成员之一不是有效地址，则 SMTP 服务器可能会拒绝整个电子邮件消息，因为它无法送达。
This may be because in our case we are using an SMTP server that is not part of Exchange, but never the less it's something to be aware of.
这可能是因为在我们的案例中，我们使用的 SMTP 服务器不是 Exchange 的一部分，但无论如何都需要注意。

In my case it wasn't working because I sent the email to one of multiple aliases that were defined for this list. It seems to me like the address that is used for display may be different than the real address.
在我的情况下，它不起作用，因为我将电子邮件发送到为此列表定义的多个别名之一。在我看来，用于显示的地址可能与真实地址不同。
The way I got it to work was in Outlook (2016) to click on the "To..." button, then in the global address book search for the ML. There were two entries, one with a globe symbol, one with a people symbol.
我让它工作的方式是在 Outlook (2016) 中单击“到...”按钮，然后在全局地址簿中搜索 ML。有两个条目，一个带有地球符号，一个带有人物符号。
Right click the one with the globe, select Properties. Here you can find the email address.
右键单击带有地球的那个，选择属性。您可以在此处找到电子邮件地址。
