Got a bit of problem at work I'm trying to fix, and was hoping someone else could she some light on the situation.

We currently use BT as our ADSL service, have our domain through 1&1 and use our own exchange email server in house.

Everything has been working ok, but since the new year we have been getting more and more returned or blocked emails. I investigated this further and found out the our reverse DNS does not match. From what I can tell BT won't/can't? setup a reverse DNS for our ADSL connection and tighter checks by other mail servers are causing our emails to bounce back because our reverse DNS won't match.

Any thoughts here people before I phone up BT and things turn nasty? :rolleyes::D
 
BT will probably charge extra to get it changed and then it will probably be a fake reverse dns. I doubt they will be able to change it from just one email. I bet at least a few phone calls and a bunch of money before you get it changed.

Last time I had to process a change it didn't cost anything, worked fine and took around 3 days. This was via a single email to them.
 
First off, good luck.

Had exactly this issue 8 yrs ago with our ISP - BT. We hosted our mail internally using Exchange 2003.

You need to talk to their networks guys, and get off the phone with the frontline muppets as quickly as possible. I had to call about 10 times to get this resolved, but it is all doable using their own systems.

Explain you have an MX record already pointing at your network, and just need an A record to do the reverse DNS lookup resolving to the same IP.

EDIT: Just noticed BT aren't your domain holders - will make life more interesting for you! I suspect all you will need to do is provide proof of ownership of the domain. A NSLookup dump of your domainname on some company headed paper faxed to them would solve that. (Been there too!)

It didnt cost us anything (maybe a one-off charge?) apart from time spent on the phone explaining to the frontline staff each and every phonecall...
 
I had to do this in 2010. They still don't have a decent control panel?

Gotta Love Zen's control panel. :p
 
Things have probably changed a lot in 8 years... and no need to "chat to their network guys" the process for changing rDNS is clearly stated in the link I pasted.
 
From memory there is a special department to email or contact via a website to request Reverse DNS changes but I don't remember it being that hard :/
