I have recently setup a new Exchange 2013 server to take the place of an older 2013 server. I have migrated the mailboxes over, changed the DNS to point to the new server (both internal and external), have uninstalled Exchange from the old server and, all is working.
That is until I shut down the old server, and mail stops flowing into the new email server from our antispam gateways.
I can only asumme that the Exchange config has a reference to the old server but I can't find where. I have checked all the visible setting on the send and receive connectors but can't find anything.
Any idea on where I should look?
