1) "//" is not a valid comment sequence in a zone file.
2) Is there any particular reason for locking your query-source to port 53?
3) Why are you defining {mail,ex,www,ftp}.accenet.com as aliases to themselves?
Perhaps you meant instead to alias 2 of the {ex,www,ftp} names to the other
one, since they all ultimately resolve to the same IP address. But that doesn't
explain why "mail" -- which resolves to a different IP address -- is aliased to
itself.
4) Likewise, defining 3 different PTR records for 119.145.59.216.in-addr.arpa
is a waste of time and resources, since nothing looks beyond the first PTR
record.
5) You need to dot-terminate the owner name of the accenet.com SOA record, or
it will be misinterpreted.
6) As a matter of style, I'd use relative ("short") names and "@" wherever
possible. Fully-qualified names tend to be difficult to read/type/maintain, and
it's easy to forget to dot-terminate them (see #5 above).
7) What's up with that "localhosts" name resolving to 120.0.0.1?
