I see there is an awesome template for Exchange 2007 to monitor WMI and Exchange queue lengths. Anything like that for Exchange 2003?
We recently had a bunch of messages piled up in a Unreachable Queue that it would have been greate for APM to notify us on.'
Also, is there anything that monitors smtp connectors? We have a connecter from our Exchange server to an Exchange Bridgehead server. It would be nice to know if that ever went down (as it did recently)
