Yes, I'm in the proces of getting a VM for mailman on its own address set up. It just hasn't happened yet. In the meantime things are complex and suboptimal. - Brian

It should not be that difficult to run a mailservice on the same machine but with a different address and name. I.e. add 44.0.0.2 to the machine, move mailman.ampr.org there, and run all SMTP services on that address and corresponding name. Then the move to the new machine is transparent.
But otherwise, it is a good idea to use virtualization as much as possible. This can be classical hardware virtualization like we use (VMware ESXi) but there are also leaner methods. That way, you can keep the different tasks on separate virtual machines, on separate addresses with their corresponding hostname, and there is also a lot less impact when one time you want to update the OS or switch to another OS.
