Provide Reverse DNS (PTR records) for Virtual Machines
Currently, 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.
For simplicity (and a quick implementation by Microsoft), I suggest that you simply provide the option for a Reverse lookup or not. So if your VM is named myserver.cloudapp.net, then the reverse lookup on the current IP would return that name.
Is this something you can do quickly? I'm having to look at alternative solutions for my Exchange Server.
