Sympl should automatically update it's configuration near-instantly
When changes are made, typically it can take up to an hour to a day for everything to have run.
It would be nice if Sympl used incrond (currently used by sympl-firewall) to detect changes to the configuration and update as needed, adding to incrond's config where needed as domains are added/removed.
This would make configuration practically instant, so would need some kind of logging/admin notification so you can see what's actually going on.
