   Is it really correct to have two names pointing to the same address.
   The way I see it, one of these names should be a CNAME entry. 

CNAMEs are 2d class internet citizens.  Many things are not legal when
CNAMEs are around, but when the suitable A records are put in their
place things work.  It is (e.g.) illegal to send mail with a 
	From: cname.domain.org
that is to say the From: line must include an MX or an A record.  Put
in an A record for the domain and the host in the domain and all will
be well.
