No worries.
We purchased a class c.
We migrated from our ISP to our own class c addresses.
Web Solutions at Fiserv hosts our website and offers DNS management.
They are responsible for our DNS updates.
Looks to me like they have not removed some PTR's and have not added some PTR's.
Once I have a clean Zone I'll let everyone know.
And we can see about any other issues that may be out there.
What I want to see is this:

Who owns/controls the IP addresses? That is who has to do the PTR records.
What is the sending IP address?
Sorry, I was out of touch this weekend so I didn't get through the whole thread
of you issue.....

It might be since it doesn't appear that my new PTR records are there.
It's like the company I am using did the A, CNAME, MX records but did not
remove the old or add the new.

The old PTR records won't cause this issue. Consider the process that is
happening......
You HELO mailout.imcu.com and connect with from 192.168.1.1
The receiving server looks at the A record for mailout.imcu.com...it must match
192.168.1.1
It then looks at the PTR for 192.168.1.1 it must return mailout.imcu.com
They are not looking at your old PTR records, they don't even know about them
anymore. That isn't your issue.

Or maybe just maybe I need to ask them to show me the old PTR's we migrated
from.
Just happened to think this morning that maybe the old PTR's were out there.
They are right there like always.
Have asked them to remove the old PTR for the old IP's.
You would think after this many years I would know to ask that type of question.

As long as you have a A record recorded for your domain the ISP should have a
subsequent PTR record

Do I need PTR records for Legacymail, outlook, and autodiscover?
