If I’m understanding this correctly, the `reply_by_email_address` should be set in the `reply-to` field of the envelope sent by the Discourse (from [yyy.com](http://yyy.com)). So when the user replies, they [reply to](https://mailtrap.io/blog/email-headers/) the `reply-to` email ([gmail.com](http://gmail.com)) rather than the original ([yyy.com](http://yyy.com)) address. So in the email response envelope, the `from` address should be the users email address and the `to` is the [gmail.com](http://gmail.com) address.

Why would the `reply_by_email_address` be used as the `from` address?
