Nslookup fails. However, yosemite.mars.lan is in the hosts file and you
can successfully ping it. It has a fixed (local) IP, which was set in the

yosemite is.

However, this is standard usage, according to the smptd.conf(5) man page.

On a LAN, you can use anything you like. I've used .mars.lan for decades
with no difficulty.
