I have installed the SparkPosts PowerMTA 5.0 and added DKIM, SPF, and other records. I need to make sure the infrastructure is built for scaling. I have a basic configuration set up.
So, I am looking for help from who had an experience with PowerMTA and email server infrastructure set up and building.
How to configure and add multi IP and Domain (current 2IPs and 2 Domains).
Connect with MailWizz(installed).
Auto install script.
