our email domain IP address was on few blacklist. I request them to remove it from their site. there was one site which charge 50euro to remove it. I had some difficulties in paying them due to some reasons. But evetually that was also cleared over the weekend.
However, still some of the domains are still not reachable. What could be cause. If this is not updated. It has been now 6 since this morning. Do you think still it requires some update time.
