Customer has scanner that sends jobs to users via email. Exchange server WAS on local subnet.
Exchange server is now cloud based (not on local subnet)
Exchange server will not accept email from Scanner for relay because it is not on the local subnet (or VPN to cloud Exchange)
Can another Exchange server (mine) be setup to accept email from the scanner via the internet, then forward it to the intended user's email address (Not on my exchanger server)
If so, how? If so, how risky?
