Hi, Sometimes it seems like a good solution to filter out all countries but your own. In fact it's not a good idea at all IMO. People do travel and they need to read and write email while they are abroad. Laptop and/or smartphone users will not like your new restriction policy when they try to get some work done while visiting a partner company in Germany. Use fail2ban as suggested by others. Mikael
