Firewall & Exchange Server DelaysLocked
We are attempting to run a Watchguard Firebox x5 with Exchange Server 2003. The server reports delays or undeliverables on most messages although some do get out. There doesn’t seem to be a problem with mail getting in, however we have not been able to leave the appliance in place long enough to really test that theory. Exchange is currently running fine with an SMC Barricade but that hardly provides the security that we need. We have tried everything that Watchguard has suggested to no end. We are connected to a static IP via Verizon DSL if that matters.
