Can I suggest we add a note to the upgrade guide:
Unless I am mistaken, upgrading postfix and mailscanner from 2.1.5 is
not possible because of the pbi configuration. I needed to remove them
and then use pkg to install them and then adjust the configuration.
My suggestion, is to basically say if you are running either of those
packages, don't upgrade from 2.1.5.
Am I mistaken?
