mails returning as spam

hello,

In our company network, we are using smtp server (postfix). We have a static IP but we receive incoming messages (pop service) from a remote service provided because of reliable uptime, antivirus softwares etc etc.

Our company's static IP has reverse dns record like mail.company.com but when it is resolved forward by the recipient's server, it shows our ISP's IP and rejecting my message.

What can I do to settle this ?

Thanks in advance
