THE SOUTH KOREAN NETWORK BLOCKING LIST

Beginning in late 2001, we started receiving vast amounts of junk e-mail (better
known as spam) from Korean networks. Some of it was in Korean, a language that
nobody here understands, some was in English. Despite repeated attempts to
contact system managers to alert them to the problem, we never received even a
single acknowledgement to any of our reports.

So, with regret, we have blocked mail from most South Korean networks.

The blocking mechanism is a DNSBL (DNS blocking list) called korea.services.net.
It lists the numeric addresses of Korean networks, in a form that mail systems
can check efficiently. See http://www.dnsbl.com/ for more info on DNSBLs.

DNSBLs are designed for software like sendmail, qmail, and postfix that handle
mail transfers from one system to another. You can't easily use them from user
programs like Eudora or Outlook. If you're not sure whether your mail system can
use a DNSBL, it probably can't. Consult the people who run your mail system and
see if they want to use it.


WHO CAN USE KOREA.SERVICES.NET ?

As far as I'm concerned, anyone is allowed to use it. Please be sure that your
mail software is set up to use a local DNS server (BIND is the most common)
rather than querying us directly, to limit the load. If the load becomes too
large, we may ask heavy users to host mirror copies of the data. (If you don't
understand these instructions, please consult the people who run your mail
system, or the vendor that sold you your mail software.)


WHAT EXACTLY IS IN THE DATABASE?

The database lists most IP address ranges assigned to Korea by APNIC, plus any
older ARIN ranges with a history of sending spam. The list includes networks,
not individual computers.

As networks clean up their act, get rid of their spammers, fix their abusable
relays and proxies, and set up a reasonable procedure to receive and act on
complaints, I have started removing well run networks from the list. My goal is
to stop the flow of spam, not to cut anyone (other than spammers) off from the
Net.

Note: The database includes networks, not individual computers. Do not write to
ask to have your computer removed, unless your entire network has its spam
problem under control.


IS AN ADDRESS IN THE LIST ?

For information about an address' entry in the list at korea.services.net, enter
it as an IP address, four numbers separated by dots, and click Lookup.

Attention Postfix Users: Did you come here because korea.services.net appears to
be blocking large amounts of non-Korean mail? Some widely distributed
instructions for setting up DNSBLs in Postfix can be misleading. Be sure that
this DNSBL is listed in a reject_rbl_client line in your configuration file.

Do not use a reject_rhsbl_client line. If you do Postfix will look up domain
names, which it shouldn't, rather than IP addresses, which is what it should do.
