I have a situation where a Win2K domain with Exchange has both domain.com internal and external users. The internal users get their mail from a GFI POP2Exchange service on the Exchange server. The external users are not within the main branch and they simply POP their mail directly from the ISP. The problem that I meet is that all mail sent from internal domain users to the external users will be kept internally in the Exchange DB and never be sent to the outside ISP. I know that there is a quick fix to this either using a policy or a DNS entry for these external users but I need to be guided in a step-by-step procedure to make the fix...
