You should put the contents of the zone file inside a CODE tag for better readability. Any way your zone file should look like this
@ IN SOA ns.server.com. root.server.com. (
2008102401 ; serial
28800 ; refresh
7200 ; retry
604800 ; expire
86400 ) ; minimum TTL of 1 day
IN NS ns.sipp4info.com.
IN MX 10 mail.sipp4info.com.
ns IN A 192.168.1.201
mail IN CNAME ns
www IN CNAME ns
ftp IN CNAME ns
Check the above and see if it works.
There are also 2 things you need to correct:
1. "ns.server.com. root.server.com." must be equal to the authoritative dns and the person's email responsible for that dns.
2. "mail IN CNAME ns". It's not correct to use a CNAME for a mail server. You can change it to: "mail IN A 192.168.1.201"
