Easiest would be to just delete the device. This problem is caused because the workstation is partially firewalled (port 135 is firewalled, but port 25 isn't)
I am using the latest version and I have quite a few workstations showing up as "Mail Servers." I had the issue before as well. How do you change the device to a workstation or do you remove it?
