	This is a sendmail issue not a BIND/DNS issue.  If sendmail
	is configured correctly to know that www00.com is local then
	it won't even attempt to lookup the MX records.

	You need to check that sendmail is even looking in sendmail.cw,
	older sendmail.cf just set the class in the sendmail.cf file.
	Also make sure you have sendmail.cw in the correct directory.

	That being said MX records (or any other record) should
	not reference CNAMES.  Also the names in the MX records 
	need to be the names sendmail knows itself by,
	sirius.www00.com in this case.
	
	Also you don't need two MX record pointing to the same
	machine.  Get rid of the one refering to www00.com.

	Also NS records MUST refer to A records.  Make sirus an
	A record.

	Also add the NS record for AUTH02.DNS.CUBE.COM as it is
	missing.
