Not so. If a name exists as a CNAME, that name CANNOT exist as any
other type of resource record. [Well, except for KEY, SIG and NXT
records if secure DNS is used, but this doesn't apply here.]

And quite right too. The name "mail" already exists in your zone file
as a CNAME, so it can't also be used for an MX record.
