On the status page, everything is showing as normal and no issues are reported. Any help will be greatly appreciated!

Hi Everyone,

Just wanted to provide an update on this.

So this issue came about when I had done a sudo apt-get update && upgrade prior to running the MIAB installer command and I believe that that had a knock on effect on the SMTP side of MIAB.

Lucky, I back up the server using Veeam nightly and had a backup so restored the VM, took a snapshot, run the MIAB installer and everything is working as expected.
