Our service needs a copy of all inbound emails from the client. This is not a problem for Exchange, Gmail and other email client - server combos.
However, our clients using HCL (formerly IBM, lotus) Domino / Notes combo are able to forward the email, but Mailgun (our inbound mail system) is rejecting the emails because they do not include the original recipient in the envelope.
Does anyone know how to forward a copy of all emails from the Domino server in a way that INCLUDES the original sender?
