Using domain server:
Name: 8.8.8.8
Address: 8.8.8.8#53
Aliases:

Host imake.ro not found: 2(SERVFAIL)
# host -t mx sometotallyINVENTEDdomainTHATdoesNOTexist.com 8.8.8.8
Using domain server:
Name: 8.8.8.8
Address: 8.8.8.8#53
Aliases:

Host sometotallyINVENTEDdomainTHATdoesNOTexist.com not found: 3(NXDOMAIN)

I read this as: imake.ro exists but is not configured.
