I have in the last two days watched hundreds of connections come in to my smtp server, all of which comes from an ISP in Taiwan.
I am progressivly just blocking large chunks of their address space.
If I had the time or the knowledge of where to find the info I would block the entire reagon. (Why can't they see the We don't relay without authentication and leave?) This can be done. There are sites such as cluecentral.net that supplies list of IPs by country (or by originating AS as well) and even talk about how you can implement such blocks. They have the IPs
