We are trying to re-engineer a RHEL 7 solution for relaying mail to MS Exchange to internal and external networks. So, currently we have four RHEL 5 boxes relaying using postfix with one of these hosts being the primary relay host. From the primary
there is an "ext"(DMZ) box that is used to relay mail to the 2 external networks.
We are trying to simplify the solution by using two RHEL 7 VM's to send to these internal and external networks. Is there a way to do this without using the "ext"(DMZ) boxes, or any solid ideas would be greatly appreciated.
