Thank you for responding. That is normally how I would set it up, but basically they have a catch all account on example.com, that sits with their ISP which SME downloads and distributes perfectly. The second account on the same domain is for their external rep. which needs to receive mail but have no other access to the network, it also provides them with a reliablity factory, where if the server or line is down he can still send and receive important mail from clients.
