Most MUA's (unix ones tended to work, not surprisingly) complain or break
on "send" but technically it works. :)
Read 2.3.5 of RFC2821 and note that "A domain (or domain name) consists of one or more dot-separated components"

So technically its not supposed to work, but not everyone is compliant with standards...
