Re: [nznog] people blocking "all APNIC space"

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?) Granted, however, this is blocking them from wasting my mailservers time deciding to reject their relay attempts. I can certainly understand the frustration that people would get. Sorry if this is off topic... I don't post here often, and will probably not again for a while. Cheers, Patrick. On Tue, 29 Apr 2003, Joe Abley wrote:

There's recurring wisdom on other lists that people outside the Asia Pacific region routinely block "all APNIC space" in order to reduce the amount of spam they receive (the most recent example was on NANOG, when someone inferred that APNIC address space was useless because it is so regularly blocked).

I've run MTAs numbered within 202/8 and 203/8 before, and I've never noticed a problem; if the practice of blocking all APNIC space was that commonplace, I would have expected to have noticed. Maybe I was just lucky, or maybe these block-happy ISPs don't include 202/8 and 203/8 in "all APNIC space".

Anybody here noticed widespread blocking of any APNIC ranges by ISPs elsewhere in the world?
