Question
Dreamhost, at&t, reverse DNS, and subdomain delegation
Here's what's going on -
We switched to at&t for an ISP. We have a managed T1 through them. We have all of our web hosting and DNS hosting for our domains (there are 7 or 8 of them) going through Dreamhost. We want to keep it that way. Custom MX records are setup through Dreamhost to resolve mail.company.com to our at&t IP address, where our Exchange server is. Incoming and outgoing mail work fine.
The problem is with reverse DNS. I searched on this forum, as well as on the DH support forum, and the consensus is that the person who owns the IP address is responsible for rDNS. Because rDNS isn't working (at&t owns our address), people at places like Comcast.net and aol.com aren't getting our emails because those companies use rDNS lookups to block spam.
I contact at&t about adding a PTR record in their DNS to reverse-resolve our at&t IP address to mail.company.com. They basically said that they can, but they won't without having our DNS hosting through them.
We pulled 3 at&t reps in the office today and my boss (the COO) went nuts on them, and asked them why our previous internet provider was more than willing to set up a PTR record for us, but at&t wasn't. at&t specified that it wasn't "best practices" under some RFC, and gave us options.
Basically at&t said that our option is to move our DNS over to them, delegate an IP to Dreamhost so that they could add the rDNS record, or be SOL. I searched and Dreamhost won't do the delegated IP w/ rDNS (which I can understand) so basically our only option is to move DNS to at&t. After fighting with the guy I finally got him to admit that if we moved only the subdomain mail.company.com over to at&t that that would be sufficient for at&t to fix our problem.
I've been searching for days but can't find where on Dreamhost.com's web panel it'll let me do this. Do I just find out the IP address that at&t wasn't me to use and set up a DNS A record and point them subdomain to them? Or is there another special process?
This has been driving me crazy and I've got 500 people breathing down my back... someone please help. :-(

Basically we let AT&T host the DNS for a domain of ours that isn't very significant and one that we don't use very much. They required this before they would talk to us any more about the issue.
FYI if you're searching on this question, I've got some advice... just stay away from AT&T. They've got schmoozy sales people that will convince people who make decisions that AT&T is turned around now that it's restructured and all of the bad parts were cut out - this is a total lie. We've received nothing but horrible service from them ever since we signed up. With problems like this, the people that are supposed to be your "support team" will give you a phone number and let you go off on your own... they won't assist with the problem at all. When you contact the party you were told to, they direct you to someone else, then those people send you to someone else, and eventually you end up where you started.
The whole thing is a big unorganized mess. When I finally demanded that our "account manager" be on the phone with me and the DNS department in a 3 way call, our account manager and the DNS department tech actually got in a screaming match on the phone with me in the middle of it. Totally unprofessional. In the end we ended up caving to their wishes because we couldn't get email out... even though they owned the IP, they refused to set up a PTR record on it in their DNS unless we gave control of a domain (they wanted all of them but I wasn't having it) over to them.
Ridiculous.
The proferred, accepted solution is unsatisfactory. There seem to be at least 2 other options that should have been explored:
1. Switching to another vendor with pros and cons documented
2. Reverse Zone Delegation and how to accomplish (AT&T delegates responsibility for the PTR record to the ISP)
It would have been very helpful if one of the experts had identified an entity that handles complaints of unethical performance by the major carriers.

that almost seems illegal on ATT's part.
It is true that anyone can do rDNS. You point A sub.domain.com -> IP (att) att makes Reverse record in their dns system and wala.
I can't believe they won't do it.
