We are running Exchange 2007 SP2. We have dedicated server roles for each role; Mailbox, CAS and HT, but we don't use Edge servers. Instead, we have decided servers running Trend Micro on the perimiter of our network. These are named TM1, TM2, TM3 etc.
Exchange Mailbox > Hub Transport > TM1, TM2, TM3 > Internet
We have multiple AD sites, some larger than others. Only some of our HT's are configured to relay external mail between the TM servers and our Exhange org.
I'm trying to work out how I can find out which HT's they are. Does anyone know how I can find that out, either using Powershell or Exchange Management Console?
