I’m using the email in feature to pull emails from mailboxes into Discourse. If the incoming email is rejected by Discourse the sender gets one of the Rejected email messages back. Because senders are not aware of Discourse as a backend on my site they just think their email was not delivered. That’s true for the Discourse site but not for the mailbox the senders email got delivered to in the first place.
To avoid confusion on senders site it would be nice to have a setting for either suppress the Rejected messages or to redirect them to an admins mailbox. What do you think?
