* chore: Remove requirement for `postfix-accounts.cf` This is an old requirement from when the change detector service was first introduced. It's no longer relevant. * chore: Do not needlessly create `postfix-aliases.cf` The config was created regardless to workaround early change detection support. No longer necessary to require the file to exist. * chore: Drop guards requiring `/tmp/docker-mailserver` to exist Legacy guards when this was the only location change detection location supported. There does not appear to be any need for changing into this directory at the start of `check-for-changes.sh` as we use absolute filepaths (originally monitored files were checked with relative paths to this config dir). * chore: Revise inline docs * chore: Add change detection monitoring for extra configs These are also handled at run-time in the current change detection support, so it makes sense to allows these config updates to also trigger change events.
