Agreed.  The mc files are somewhat more human-readable, and easier to
version control.  Plus the syntax of cf files is not exactly easy to
understand and I always worry about breaking something.  At least with
the mc file, if it compiles I know I haven't made any syntax errors.  I
think most sendmail admins would agree that you should modify the mc file.
