I was thinking MX should not be a CNAME record.
But these two are broken the rules, and they seem work just fine?
2008.sina.com. 52 IN MX 10 mx.2008.sina.com.
mx.2008.sina.com. 8 IN CNAME freemx1.sinamail.sina.com.cn.
freemx1.sinamail.sina.com.cn. 8 IN A 220.127.116.11
mail.china.com. 391 IN CNAME mail.china.com.cachecn.com.
mail.china.com.cachecn.com. 191 IN MX 10
