我希望有人可以告诉我，如果我配置错误或者这是一个Heroku错误。
当我通过电子邮件向某个大学的某个人发送电子邮件时，该电子邮件会以某种方式在电子邮件地址中添加一个herokuapp扩展程然后，当人们尝试回复时，它会反弹，因为该电子邮件不存在。下面是一个例子。
我希望我的CName配置错误或其他什么。我没有使用A记录，所有CName记录。我的第一个CNAME记录是@记录，其值为challengage.herokuapp.com。
如果你能提供帮助，请告诉我！非常感谢。

您在Heroku应用程序的外发交易电子邮件中配置了错误的地址。
您在chalengage.com和无法接收电子邮件的heroku应用challengage.herokuapps.com上拥有有效的电子邮件配置。
您需要将外发电子邮件地址更改为paul@challengage.com
在Rails中，您可以通过添加/更改ApplicationMailer配置来配置ActionMailer::Base类（子类default from）中的地址的外发电子邮件：
default from: "Paul Klopfer <paul@challengage.com>"
