Naresh, Get your basics right first. There are multiple reason for this and few are directly related to Postfix. If postfix is open relay, it hardly takes 2-3 days for the mail server to get blacklisted.
By the ways, as other other has already mentioned, below are the reason that can cause the issue. 1. Blacklisting in RBL/DNSBLs Server (use robtex.com to check) 2. Absence of PTR Record. 3. Wrong SMTP Banner. 4. Subnet may be in a pool which has mail server as open relay server (very common). 5. SPF Record. 6. The Server may be a real source of SPAM (quite possible that you are really spamming). 7. Proper CNAME if A Record is something else. 8. Opt In and Opt Out option for Subscribers if you are using the mail server for Email Marketing. 9. For complete consultancy and solution, user needs to pay me [Commercial].
