I tried everything I knew about. I installed my own DNS server for zimbra mail server including spf record, DKIM with dkim-milter, MX record,and reverse DNS.Outgoing mail from our mail server are going to Inbox folder on gmail and rediffmail, but on hot mail and yahoo mail they are going to spam.
Can anyone please tell me what is the problem? I also used following site to perform various mail server test but couldn't figure out anything suspicious except email header:

Following is the full header of email that went to spam folder on yahoo:
