I have a Linux (Ubuntu) virtual machine running on Azure and this machine runs a website that sends email to registered users. This emails are greylisted on some mailning services.
After some research, i realized that most probable cause is missing PTR record.
Next step - i start searching for means to create PTR record for my server. I've found this article http://azure.microsoft.com/blog/2014/07/21/announcing-reverse-dns-for-azure-cloud-services/ . It says, that it is possible to create PTR record by using azure PowerShell.
I`ve downloaded and installed azure-cli, that is a linux command line interface to manage azure services and resources. Unfortunately, in azure-cli there are no command to add PTR record for cloud service. Web-interface does not have such functionality either.
Is there any way to create PTR record for linux vm on azure?
