I'm about to inherit a situation where an exchange 2010 is configured in the following way; I have a device, some sort of gateway, that sits in front of two exchange servers that is supposed to shuttle to one of those server depending on what the request is. One of these servers handles the mail boxes and the other handles the data.
The problem is the users are not able to receive email from the outside even though the MX record have been created in DNS. This is how the environment was described to me. Can anyone help me troubleshoot this issue?
