So "something" is the real thing (a machine) and "otherthing" is an
alias for that thing - and an *alias* can not have another RR record
attached (which in your case is an MX record). Only real things can
have further RRs (attributes).
The wording of the CNAME definition is in my eyes very confusing. The
above is how I would describe it.
