I have an assignment to install and configure postfix on azure. Using my installed and working VM server and my VM client. I have 2 fully working VM's on Azure. With iptables setup to accept ports 22 and 53. Installed bind-utils. After creating iptable rules......I still cannot send mail successfully outside of my private network or outside. Need someone familiar with Azure that can walk me through the correct steps.
