捕捉电子邮件反弹 [英] Catch email bounce

问题描述

我将发送合法的电子邮件到收件人列表，其中一些可能已经过时了。

I will be sending legitimate emails to a list of recipients and some of them are probably obsolete by now.

我想知道，根据电子邮件反弹，这些都是过时的，并将其从数据库中删除。除了 VERP ，我还没有看到任何标准化的任务。

I wish to know, based on the email bounces, which are obsolete and delete them from the database. Except VERP I haven't seen anything standardized for this task.

有没有其他方法你知道？

Is there some other way that you know about?

推荐答案

没有别的方法比VERP。 DSN电子邮件很好地提取了反弹的准确原因，但并不是所有的服务器都发送标准的DSN邮件。除此之外，DSN邮件可能会被伪造，这可能是一个问题。您可以向VERP地址添加简单的数字签名。

There is no other way than VERP. DSN mails are good to extract the precise reason of bouncing, but not all servers send standard DSN mails. In addition to that, DSN mails can be forged which may be an issue. You can add a simple digital signature to a VERP address.
