Hi Doug, Thank you so much for demystifying this for me. It's nice to know that I shouldn't see this again when I move the server.
Considering that this is a known issue and that it required a complete re-install to recover from, I must recommend to IPSwitch that the documentation be updated to provide sufficient warning and not merely relegate this info to the knowledgebase. By the time I went to the knowledgebase, the damage was done. Specifically, "Chapter 2: Installation -- Checking Your Primary Host Name" should clarify that dynamically-assigned (DHCP) IPs are not acceptable -- that a static IP is required. I hope this recommendation is helpful to IPSwitch. Thanks again, Doug. Dave Mail Administrator wrote: > > Dave, > > You should have had static IP's assigned in your test environment.
