I would like to understand the settings better as SBS tends to do a lot of the settings for you and this makes troubleshooting more difficult.
on the Server - Hub Transport - Receive Connectors - default Servername properties :
Under the "use these local IP addresses" is the local IP address of the server. This I understand to be this connector is allowing the SBS to connect to Exchange for whatever SBS needs to send. (am I correct?)
Under the "Receive mail from remote servers" I have one server that has the local network range minus the Gateway address. Which I understand to be blocking the outside world. (am I correct?) This server has some issues with Backup Exec notifications (they do work but only to a local address)
But I have another server that I look after that is the opposite to this and has everything but the local network????? This server has no problems with things like BackupExec sending notifications etc
Both servers seem to have a similar setup on the "Internet Receive Connector"
Under the "use these local IP addresses" one server has the local IP the other has "use any available IPv4"
Under the "Receive mail from remote servers one has the whole of the outside world and the other is similar apart from some errors in the addressing due to an IP change on the server during build
If there is a resource out there that explains the roles and how they SHOULD be configured and why then I would be very gratefull
