But anyway I thought we were talking about the localpart.
No, I was talking about the domain part.
The standard is pretty clear that the LHS can have anything in it you want, as long as you quote it.

No; domain names that end in a dot are referred to in jargon as "terminated" or "rooted". At least, the jargon I'm used to...

Well, diagnosing local DNS configuration, mostly. A name that does *not* end in a dot is supposed to be an invitation to apply the search list from /etc/resolv.conf.
With people having things registered like com.com and edu.com, it can get a bit wacky.
