Um, okay. Let me see if I'm understanding this correctly. The FQDN of your mail server is mails.coreteamsolutions.in which resolves to 207.106.22.3. Your MX record points to that FQDN, but it's actually a CNAME. That's problem number 1. MX records aren't very happy with CNAME records. You need to get your DNS provider to make it an A record instead. I'm not sure what you are expecting with the 192.168.1.202 resolution. That is private IP address space. As far as the internet as concerned, that IP address doesn't exist. If you need that IP address to resolve, you need to make your DNS server authoritative for that zone. No amount of magic is going to make that work without you being authoritative. If you are trying to make sure that your foward and reverse records match, you are going to need to get RapiDNS.com to change the PTR record for 207.106.22.3 to resolve to mails.coreteamsolutions.in. They own that IP address space.
