The prior weekend our mail server was moved to a completely new place, so we also decided to shut down the old mailserver.
However, the old server contained important files that handled the blacklist functions (methods that automatically updates and changes the zone data in the zone tornevall.org). As this service has been shut down, an update for the DNSBL API has been deployed since we have been unable to rewrite zone data since then.
This also means that all removals from the removal interface should be instant if everything goes as planned (tests has been successful) – and not hourly.
Just remember that even if removals are instant, your blacklisted IP may still be present in caches around the workd, and won’t be updated instantly.
