I have two external MTA (2 linux server) and both of them receive mail from external domain and relay to my internal Exchange Server. I've configured the Exchange to use as smarthost the first MX. But how can I use the second MX as smarthost (in LOAD BALANCING mode with the first smart host) ?
How can I configure my Exchange 2003 to use the second MX as a second LOAD BALANCED smarthost? Have I to configure more SMTP virtual server ????
Thanks in advance.
