Guidance on usage: iRedMail on Ubuntu 20.04 Minimal

Configuration and Connection to iRedMail on Ubuntu 20.04 Minimal

  1. Static IP address – Your virtual machine should have the static IP address if you want to constantly change the domain settings (because if the address is dynamic, after the rebooting of the machine it’ll change to the static one).

You should allow access by port TCP25, 80, 110, 143, 443, 587, 993, 995, which you can do in the properties of the Azure firewall network.
