Hi, some of my client email are returned me and having the issue with PTR record.
We do have exchange 2010 in house to send email and having the pop server on mail hosting company to receive email through pop connector on exchange server.

this is the error we getting:
Your server IP address [209.151.130.209] does not have a valid reverse DNS entry [broadband-net130-ip209.ica.net]

I  called our ISP to fix the rDNS, but he asking me to provide rDNS record for the IP which your mail server is using.

i don't know, what i should do from my end. As i mention, incoming email coming from mail hosting outsource through pop connector, and outgoing using our exchange 2010 SMTP.

Please help...
