我怎样才能在.NET实现VERP（可变信封返回路径）？ [英] How can I implement VERP (Variable envelope return path) in .NET?

问题描述

我想implamant在.NET这种反弹的处理协议，但之后我研究升技我发现了附带.NET不支持VERP要求信封分配的基本类

I want to implamant this bounce handling protocol in .NET but after I researched abit I found out that the basic classes that come with .NET don't support envelope assignment required by VERP

有没有变通或者其他的方法？

Is there a work around or another method?

推荐答案

您绝对可以VERP使用实施 System.Net.Mail ，只是生成一个唯一的从地址，每个到地址，然后在消息反弹，你的包罗万象电子邮件帐户将得到它，你就会知道什么到地址无效。

You can definitely implement VERP using System.Net.Mail, just generate a unique from address for each to address, then when the message bounces, your catch-all email account will receive it and you will know what to address to invalidate.

下面是一个一步一步的例子：

Here's a step-by-step example:

1. 您将发送电子邮件至 [e-mail] 。
2. 您生成一个GUID一个随机的唯一从地址，例如：     [e-mail]
3. 您保持这种关联以上的到地址从地址字典或数据库表。
4. 您收到一个反弹邮件到包罗万象收件箱，其中recepient是 F9168C5E-CEB2-4faa-B6BF-329BF39FA1E4-客户@ MYDOMAIN .COM ，因此...
5. 您废止 [e-mail] 在你的数据库。

1. You will send an email to [e-mail].
2. You generate a random unique from address from a GUID, for example: [e-mail]
3. You keep a dictionary or database table that associates the from address above with the to address.
4. You receive a bounce email to a catch-all inbox where the recepient is [e-mail], therefore...
5. You invalidate [e-mail] in your DB.
