Hi All,
I hope you are good. I noticed a high dropped number of subscriber in the mailgun dashbord, is this related to GDPR and then normal ? Or did i do something wrong ?
Did i miss an annoncement ?
Many thanks

Those are essentially bounced emails if I understand it correctly. Not sure what the cause would be though. I would check the logs and or contact Mailgun Support.

You can filter the Mailgun log for those messages, then see in the summaries what the prevalent issue might be.
If you are on a shared IP address at Mailgun, it’s possible that another account caused it to be blacklisted by one or more of the common email services which would affect deliverability to your users on them.
Mailgun support is pretty good about switching you to a “less noisy” IP address if that happens.

@Jeremie_Leroy，你收到 Mailgun 的回复了吗？

你好 @codinghorror，
不完全是，但看起来现在已恢复正常。不过行为有所不同：现在它每周只发送一次邮件，数量也不再显著增长，状态相当稳定。
我还尝试了专用 IP，本以为会有所改善，但我不太确定效果如何。
如果还需要我提供更多帮助，请随时告知。
祝好，

当然，当用户在 Discourse 中创建账户时，电子邮件在那一刻肯定已被验证有效，因为在 Discourse 中，电子邮件等同于身份。
但电子邮件账户可能会随时间停止工作，或者在用户迁移场景中，用户虽能登录，却已无法控制其旧邮箱地址等。
因此，统计邮件退信（如果已配置）的过程在这些情况下尤为重要：

>
> I can’t find anywhere in Discourse admin panel where I can find full details of bounced emails – to read the content and find out the bouncing reason. I don’t seem to have those saved in my email account (automatically deleted by Discourse?)
> [@Notify users of bouncing email](https://meta.discourse.org/t/notify-users-of-bouncing-email/88895):
>
> I’ve been manually going through bouncing emails for a while and PM-ed the affected users to ask them to check their email settings. Without fail, they did not realise they were using an old email address and updated their profile. It would be useful if Discourse could automatically send these users such a message.

是的，现在已恢复正常。我之前只遇到了“永久失败”。我现在已添加了“临时失败”。
感谢 @codinghorror。
