Unfortunate, as you said, it only alleviates any receiving MTA using a filter that doesn't check for PTR, or if it does, and finds that it's a DHCP pool (whether or not it is because some statics are actually reserved DHCP pools within the ISP), it may still flag it as residential.

I talked to the Centurylink guys again last night. They took over from
Embarq. The last tech I talked to did not even know what a reverse PTR
record was! His answer was to get a email address from them and use that.
Yea right! And yes they handed out a address pool of IP's. Thanks to all for
your inputs and advice.

I do not think it is called a reverse PTR. Either reverse DNS or PTR.
If he doesn't know then you ask for the next person.

I'd keep after them. See if you can get somebody who actually knows what
this is about. If they are going to offer fixed IP business-class service,
they need to be able to do this.

I called Embarq last night and guess what? They transferred me to
CenturyLink. I did get a tech who knew what I was talking about but stated
again that they do not setup reverse DNS. He stated the best way to correct
this was for the client to use embarq.net email addresses. I told him the
company owner will be real thrilled at hearing that and to expect a call
from him on Monday.
