Hi
@iworx-brandon - sorry I may have been thinking over something else re email user but certainly for domains or entire server it is correct, and if domains, can be set to route to different smarthosts (on any port with or without authentication credentials - you just tell it the smarthost to use with port and authentictation for each domain)
This post probably makes it clearer and it was some time ago, but still works today.
Also worth mentioning that the domain does not need to be a siteworx account on server, it coudl easily be outlook.com or live.com or gmail.com etc… and will route these to smarthost you tell it too
Many thanks
John
