We are struggling with sending purchase orders using Infor Document Managment due to the fact that by default, they will come from Infor's domain instead of our company's domain. Vendors would be wary of getting a purchase order from a domain NOT related to our company. In trying to use our own domain, Infor's only solution seems to be using SMTP relay. The problem with this is that the IP address they use is not dedicated only to our company, so our messaging service has some requirements to ensure the messages are valid. I'm not very technical in these areas, but I think something along the lines of "x header" or placing some code in the message body to ensure it's valid. Infor seems to be struggling with this and making it sound as if this would require development.
How are other companies handling this? Surely not everyone is just sending documents from IDM and NOT using their own domain, are they? Help please!
