Technically (and I think that the other responders have the same idea),
it is not "an example of 'CNAME can point to an MX'".
It is a CNAME and an MX record pointing to the same RHS nodename.
I believe that if you had
foo IN MX 0 mail
mail IN A 192.168.1.10
bar IN CNAME foo
where there was no "A" record for "foo", then this would be an invalid
configuration. I am not sure what "pointing to an MX" really means.
