Team,
Trying to configure our new Exchange 2013 server to allow external clients (MFPs / Customer Printers) to use our internal mail server as an authenticated SMTP relay.
We have a secured server, and have in-house email working great, internal devices who's IP is listed on our internal receive connector can scan to email both internal and external.
We wish to offer some of our clients an SMTP Relay service where we control the account used, and when they use our MFP with our email server info, they can relay "scan to email" through us.
I am unsure how to setup a special receive connector to allow external relay, not open, but authenticated on a dedicated port.
Any suggestions?
