The reason why MX records may not point to CNAMEs is to avoid loops or
other errors that might occur if CNAMEs are misconfigured.  If you want
to avoid errors where information is duplicated, use a templating system
to generate your zone files.  With a little effort, you can create
something that will generate your forward and reverse DNS zone files
from one set of records, as well.

If you have Perl skills, Text::Template or Template Toolkit are good for
this.
