Navigate to c:\vm and right click on c:\vmservice.exe. Check the file version. It should be 12.1.6086.xx. If .xx greater than.05, try adding the following to the vm.cfg

smshost email address = [email protected] (or whatever your ISP expected name@domain is). Spaces are optional and better if not used.
Reboot. If the system doesn't come up, the version is wrong. No help. If it starts,. see if the ISP aceepts it. Sorry .. no option for password (I would think each mailbox would have its own credentails... not the VM itself).
