El pie de página del correo dice: "Visit Message to respond to .", sin nombres después de "to".

[pmusaraj (Penar Musaraj)]

This should be fixed now @cultiv, the system messages should now output “Visit Message to respond” in emails. We may follow up by removing that line altogether, because, well, there isn’t too much value in responding to system messages.

FIX: do not add `_pm` suffix to locale key when email is from system user
