You should probably take the default options used in /etc/named.caching-nameserver.conf and replace whatever you have in named.conf.

This is the results of  named-checkconf -z

zone maizenblue.com/IN: maizenblue.com/MX 'mail.maizenblue.com' is a CNAME (illegal)

Your MX record must be a hostname that resolves to an IP. That is, you have something like:

maizenblue.com.	MX	5	mail.maizenblue.com.
mail.maizenblue.com.		CNAME something

Instead, you must use:

maizenblue.com.	MX	5	mail.maizenblue.com.
mail.maizenblue.com.		A 1.2.3.4

Some mail servers will not deliver mail to you or accept your mail, as your DNS records violate the relevant RFCs.

zone maizenblue.com/IN: loaded serial 2007041818
zone 10.10.10.in-addr.arpa/IN: loading from master file 10.10.10.zone failed: file not found
_default/10.10.10.in-addr.arpa/IN: file not found
looks like it can't find the reverse zone file, however it is definitely there....Any help would be greatly appreciated...Thanks

I'm not sure about that one. Maybe an SELinux issue? Check /var/log/audit/audit.log
