I believe that RFC 2822 only allows news at clerew because clerew may be a
top-level domain.  This language at least sounds like it's expecting all
domain names to be FQDNs:

   The domain portion identifies the point to which the mail is
   delivered. In the dot-atom form, this is interpreted as an Internet
   domain name (either a host name or a mail exchanger name) as
   described in [STD3, STD13, STD14].
