CNAME and OTHER data error

You can't have a CNAME and an MX record for "mail", once you have a
CNAME you may have nothing else for that name. Should be:

www	IN 	CNAME		@
mail	IN	CNAME		@
@	IN	A	x.x.x.x
@	IN	MX	10	@

"mail" and "www" will adopt the MX record of "@" by virtue of the
CNAME. Mail send to any of the three names will go to "x.x.x.x". This
is ideal in most situations. Some RFC's suggest your domain (@)
should accept mail.
