Hello,
I have gone through the requirement and understand that you would like to open port 25 in your Azure VM. Kindly note that by default most of the azure subscription will have port 25 restriction inorder to avoid spam mails generated by their platform. Could you please provide below information so that we can figure out the exact reason and help us to get unblock port 25?
1. Do you Enterprise Agreement subscriptions?
2. If Enterprise Dev/Test subscriptions, port 25 is blocked by default then we need to remove restriction from Azure portal.
I will be available between 9:00 AM IST to 11:00 PM IST. If you want me to be available in different time then please let me know.
