First of all what DNS server are you using? BIND?
If so your PTR zone is completely wrong. Your "forward" zone file also has a few problems that are causing errors. Another thing... the filename itself is important in BIND so I am only guessing at the file names you have (What I am showing below is what they should be if not). Try changing them to something like these:
`educationyug.com`
Code:
$TTL 38400
@ IN SOA ns1.educationyug.com. admin.educationyug.com. (
070725
604800
86400
2419200
604800 )
educationyug.com. IN NS ns1.educationyug.com.
educationyug.com. IN MX 10 mail.educationyug.com.
educationyug.com. IN A 10.0.0.1
ns1.educationyug.com. IN A 10.0.0.1
mail.educationyug.com. IN A 10.0.0.3
`0.0.10.in-addr.arpa`
Code:
$TTL 38400
@ IN SOA ns1.educationyug.com. admin.educationyug.com. (
2006081401
10800
28800
604800
38400 )
IN NS ns1.educationyug.com.
1 IN PTR ns1.educationyug.com.
3 IN PTR mail.educationyug.com.
