I had gone for IP reputation, something like checked for blacklisting resulted positively was not blacklisted.

Can any one please suggest me the solution or show me the right path to solve this.

Answer 1

If you don't have an SPF (Sender Policy Framework) set up on your domain, you should do that. It will allow your recipients' mail program to verify that whomever is sending mail through your domain is permitted to do so, thus less likely to be flagged as spam.
