Any way to enable Reverse DNS for a Virtual Machine?

I have a Windows virtual machine and Azure provides a DNS entry for it (e.g., This is great so I can always reach my VM.  Unfortunately, apparently there is no corresponding PTR (reverse DNS) record created.

As such, you cannot operate a Microsoft Exchange Server on Windows Azure. Well, you can, but don't expect to be able to send email to anyone on AOL, Comcast, and a multitude of other domains. The reason is that these providers REQUIRE that the sending IP address have a reverse lookup (PTR record) for the IP address from which email is being sent.

For simplicity (and a quick implementation), I suggest that there simply be a yes/no option for a PTR record (reverse DNS).

Looks like Amazon provides Reverse DNS... for exactly the reasons I need.

Thanks for highlighting this feature request. We've known this request and are working on it. However at this point we don’t have a timeline when it will be made available.

This is the last feature we need to close our dedicated server and complete the migration to virtual.  Fantastic product, but without reverse DNS you can't move mail servers.

Same here. This is badly needed to complete migration from another provider. If you have a beta list for this feature, feel free to add me for more feedback.

Yes, please.

I might  have to move off of Azure because I can't run a proper mail server if AOL won't talk to me!!!!

Please let me provide a reverse DNS address so this will all work.

This is something absolutely needed. I'm considering Azure for migrating a server that needs to send email to users with notifications as part of the features of one App and without this I won't be able to do it.

Add this ASAp, please :-)

I did not think Exchange was supported on Azure.  Can someone from Microsoft please confirm?
