thats what I want to do, have the mail server relay for them. I have a subnet on our network set aside to relay email for our domain. For ease of management theyre open relays with firewall policies dropping any traffic to them not from authorized hosts, same as setting the subnets but managed externally.
But I need to make sure the emails coming from the mikrotiks come from authorized IPs, otherwise of an OSPF path changes the presenting IP will be whatever that interface is.
