I think you misunderstand. As I understood,
HR@example.com is a distribution group or something similar. It isn't a real email box, but emails sent to that email address are automatically sent to all members of that group. Sending an email to
HR@example.com would cause this email to be sent to all group members. You can't expect those to reply back; some may not care, some may not understand, and some may even no longer be active.
