如何使用System.Net.Mail设置反弹地址？ [英] How to set the bounce address using System.Net.Mail?

问题描述

我想实现可变信封返回路径（VERP）的方法来管理电子邮件地址（即当邮件我发弹回我希望它被发送到一个特定的电子邮件地址，以便我可以更新我的数据库，以避免发送电子邮件，该电子邮件地址在将来）。

I'm trying to implement the Variable envelope return path (VERP) method to manage email addresses (ie when an email I send bounces back I want it to be sent to a specific email address so that I can update my database to avoid sending emails to that email address in the future).

根据这篇文章，可以指定电子邮件地址的反弹电子邮件发送给。你如何在.net中做到这一点？

According to this article it is possible to specify the email address a bounce email is sent to. How do you do this in .Net?

例如说我（[e-mail]）要发送一封电子邮件给您（[e-mail]）。如果[e-mail]已经不存在我想yourserver发送反弹邮件给bounce-you=[e-mail]）。当我收到这这种方式退回的电子邮件我知道[e-mail]是不是一个有效的电子邮件地址了，我可以相应地更新我的数据库。

For example say I ([e-mail]) want to send an email to you ([e-mail]). If [e-mail] doesn't exist anymore I want yourserver to send the bounce email to bounce-you=[e-mail]). This way when I receive this bounced email I know that [e-mail] is not a valid email address anymore and I can update my database accordingly.

在这个例子中，弹跳地址将是：bounce-you=[e-mail]
如何使用System.Net.Mail指定呢？

In this example, the bounce address would be: bounce-you=[e-mail]
How do you specify it using System.Net.Mail?

推荐答案

底线是，你不能在.NET中做到这一点。您只能设置发件人地址，这System.Net.Mail也将作为信件来自使用。

The bottom line is that you cannot do this in .NET. You can only set the FROM address, which System.Net.Mail will also use as the Envelope-From.

要做到这样的事情，你需要使用第三方SMTP对象就像我写了一句：

To do something like this, you would need to use a 3rd party SMTP object like the one I wrote:

http://www.aspnetemail.com

在aspNetEmail，你可以这样做：

In aspNetEmail, you can do something like:

EmailMessage msg = new EmailMessage();
msg.ReversePath = "[e-mail]

aspNetEmail将在SMTP会话期间使用MAIL FROM命令的ReversePath值。我可以很容易的被称为这个属性ReturnPath这样或EnvelopeFrom。现在回想起来，EnvelopeFrom会是一个更好的名字。

aspNetEmail will use the ReversePath value in the MAIL FROM command during the SMTP Session. I could have easily of called this property "ReturnPath" or "EnvelopeFrom". In retrospect, EnvelopeFrom would have been a better name.
