Reverse DNS for Exchange

Hello

This might be a dumb question so please bear with me!

Just started at a new company and need to get my head round reverse DNS for
Exchange. Currently it is not setup and many emails fail.

The company hosts it's own DNS servers for the domain. The domain (the
public xxxx.org) is at the ISP but the nameservers are here and I have
control of them. The ISP has simply pointed the nameserver records to
servers here.

I don't have a lot of DNS experience but get by.

Can anyone offer any advice and steps to follow to setup a reverse DNS for
my mailserver please. I assume since we host the DNS that we need that
here?

In the past I have always had DNS for the domain name hosted at the ISP so
they made any changes like this, so this is new to me.

Thank you in advance.

If you're referring to the reverse record for your IP address (a PTR
record), you will need to ask your ISP to create one. They own the IP block
and have control of it. Not many will delegate that out to customers. Give
them a call. :-)
