Yes, this is quite normal. Imagine how much comes in to the country gateway and gets dropped... The internet is full of people who only want to destroy it and there is not much that can be done about it. People use spoofed sender addresses (their provider should block that but many providers don't care), and others like to scan for all kinds of situations they can abuse, e.g. for DDOS. You need a good firewall. But maybe not what Tom suggests, because that ends your connectivity with the non-44 part of internet. Rob
