While they still maintain control of the IP address space registered with ARIN, ATT does have the ability to delegate reverse DNS resolution to their customers. They have delegated multiple class C address spaces that we use to us and we use DNS Made Easy for reverse resolution. It works flawlessly. Inexpensive and customer service is always great, plus they have a global Anycast network providing 100% uptime SLA.
Of course, getting ATT to make the delegation may be easier said than done in your area too ... :)

PTR is the reverse pointer for an IP Address.
If ARIN has assigned the IP of 1.1.1.1 to AT&T (place the appropriate ip of course in place) then the only organization that can set PTR is AT&T.
PERIOD
What you can do however is create a smtp server using EasyDNS or other services and then have your outgoing mail actually tunneled through their ip - which they in turn control the PTR for.
I would suggest however - calling AT&T directly
Dial 1-888-613-6330, Prompt 3, then 1.
ATT also has their online provisioning tool here http://dpt.ip.att.net/mis_dns/index.html

At my previous employer we had the same exact problem with our service provider and the way we overcame it was to move all of our DNS services to EasyDNS. They provided the PTR records as well as all of the standard DNS services. The other advantage is that anything to do with DNS was handled by one company and it wasn’t dependent on any service provider. So if we found a service provider that offered better services for a better price we could move to them without worrying about who would handle pieces and parts of our DNS needs. If EasyDNS provides such services, I’d be willing to bet there are others as well.

The “owner” of the IP address (ATT) is the master of the reverse DNS. If they won’t change it doesn’t matter what a 3rd party DNS service is set to.
Say bye bye to AT-T if possible. We moved off of them long ago as well as I’ve moved 2 clients off of AT-T. In Chattanooga Comcast is a surprisingly great service to go with for small business, but for more demanding needs our power utility (EPB) offers fiber internet.
I don’t know where you are, but in the past when I lived in Atlanta I moved my company there to Cbeyond communications from AT-T (both data and phone). It was a great move. I can’t speak to Cbeyond’s reputation now (that was over 5 years ago) but check them out if they are in your area.
If I recall I went with the Beyond Voice package.

EasyDNS is easier and cheaper to work with than Network Solutions.

You may want to look at EasyDNS.com <http://EasyDNS.com> . They have a reverse DNS service available, along with the regular DNS services.

Thanks for the feedback. That’s what I expected too but was told “no.”
How long ago was your exchange with them? This could be new policy. Lots of frustrated folks on the ‘net about this but I just can’t move this domain to ATT in the middle of the week. I shouldn’t have to anyway…like they are holding me hostage.

I don't know about the specific IP Flex service but I've had AT&T do a reverse DNS entry for us in the past to our mail server for the church. We have Domain registration with Network Solutions, Web hosting on a different provider and our reverse dns entry from AT&T (Bellsouth is who has it listed).
All I had to do was send an email to an address that AT&T gave me and they made the dns change.

So we recently moved 100% of our Internet services to AT&T "IP Flex" service. We're having an issue with Reverse DNS when trying to send emails to some domains that do the rDNS lookup on each message because we don't have it in place.
I've tried SPF, TXT, SRV, etc. - no dice.
Domain registrar is currently Network Solutions.
AT&T won't create a PTR record for me pointing back to my mail server unless they "host" the domain for me, which I don't want to do for multiple reasons, including the downtime that such a move would incur.
What can I do? Is a SmartHost an option? I'm not familiar with them but am desparate now and ATT is not being at all flexible.
