Reverse DNS not forwarding to ISP DNS
We have a receiver mail server refusing an email from us with message Received: 553 We do not accept mail from IP addresses without reverse DNS.
Our inside DNS seems to have all the entry to answer direct or reverse calls for our email server.
It seems that our ISP DNS server doesn't have the entry as if their DNS table weren't update from ours.
My 2 parts question is
1- Where is the misconfiguration on our side or on the ISP side?
2- If it is on our side, where to configure it on our DNS (windows 2003 with Microsoft DNS) so that it can populate the needed data for it to work?

Answer Wiki:
You will need to reach out to your ISP and indicate you want a reverse IP for publicmailserver.fullyqualified.domainname.
Sample e-mail you would want to send:
Dear {ISP Account Contact}
Please add a reverse DNS (PTR) entry for {publicmailserver.fullyqualified.domainname}. - 123.456.789.012
Regards,
{Your Name}
