SMTP Relay - Copy mail sent from specific IP address
I am running Exchange 2016 Full Hybrid. I have a monitoring solution that sends mail through the Exchange SMTP relay in Exchange 2016. This monitoring system is whitelisted by IP on the relay but might send from several addresses. I want to get every mail sent from that IP address through the relay copied into a shared mailbox either in the on-prem Exchange 2016 or ideally into a remote mailbox on the hybrid in Exchange Online. How can this be accomplished?
- This can be done with a mail flow rule and the IP range criteria I found.
