Hi,
Running Exchane 2013.
So we have internal email relaying working (network equipment bouncing of our exchange server) but we have a software product being hosted outside of our organization that needs to relay off our exchange server. What are the proper steps for this? All I can find is anonymous relaying. I am guessing, they are going to need a domain account for this work. Would like to get some best practice steps if possible.
TIA
