Post #3035139

@courtney Seconded on both counts. While I knew the change was coming, the dovecot package on a rolling release platform updated without me noticing until I tried to access the service. The combination of change in both the syntax and the directives made this surprisingly difficult until I finally realised how the new syntax enabled the config to be structured multiple ways depending on how you want to group the directives. `dovecot_config_version` and `dovecot_storage_version` go at the top.
