Setup an SMTP Relay for Scanner to Domain Users

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?

have you tried adding the SMTP address of the cloud? Have you looked at DNS to see if it has an entry for the Cloud?

Did that, but the cloud vendor has set their system up so as to NOT relay from anyone the internet.

as long as your office has a static IP address they could add an exception and allow relaying for your ip address which could solve your issue.

I will try that, but they have indicated a great deal of inflexability during my previous attempts to resolve the issue with them.  It certainly would be easier.  In anticipation of no flexability on their part, I am attempting to craft a Plan B here......

Well I assume that the domain is the same on the now cloud platform, you could set your local exchange server to allow relaying, you would just need to make sure it doesnt have the same domain name still configured as it would try to deliver locally. Then just add an spf record to say your office IP is allowed to send mail based on that and your cloud server should accept it from your exchange server. Although the sender email may be slightly different. Or you could configure an smtp server on your network that just allows relaying and doesnt do any email account management so that it can just be used as a local relay to forward mail onto the net again with an SPF.

I believe this soluton would probably work, but I ended up using a 3rd party SMTP relay (MailJet.com.
