Walling off Asian E-mail to Prevent Spam
SomeoneYouDontKnow writes: "Seems there's been lots of spam news lately. This piece from Wired describes how frustrated sysadmins in the West are responding to a torrent of Asian spam by simply refusing all e-mail from that part of the world. As anyone who's ever reported spam to Asian ISPs can attest, getting a response of any kind is almost impossible, so some ISPs are simply giving up on receiving any mail from them. Setting up barriers like this is regrettable, but when the originating ISPs refuse to take responsibility for the actions of their users or close their open mail servers, there would seem to be no other choice. Has anyone ever had any kind of constructive conversation with one of these ISPs to see why they are unable or unwilling to do anything?"
Sure, why not. Heck, I blocked France on principle!

Is this why my mail order bride isn't writing back to me?
Cultural issues also contribute to the problem. Many spammers in Asia say they do not understand why spam is a problem.
"It's a sign of respect that someone sends you an electric business card. It means he wants you as a customer," said Zhao Peng, owner of a computer store in Hong Kong.
So what does it mean when they hammer your firewall all day long?
They're just being considerate in checking you for exploits? (Most scans originate from asia in my logs.)
what you don't know is that the client was hunted down and shot.

legitimate use of a DDoS attack. I know it is wrong on so many levels and immoral and all that, but doesn't it just make sense on a primitive level that if they are unwilling to shut down their open relays, someone else should shut them down for them? 24 hours notice, then hit them until they promise to shut it off. Make there be direct consequences for them not playing nice on the net.
Like I said, I know this is inherently flawed, but it is nice to dream. Mmmmmm, vigelante justice on the net...
And while we're at it, we should make it illegal to respond sarcastically to extremely simplistic solutions to complex problems! Yeah!

Yes, i have a taiwanese pen-pal that i write configuration tutorials for in flash5.0 and in the native language. and since i am so rich i send my lunch money everyday to africa. and working in the tech industry leaves me with an abundance of minutes to relax when i get home before i go to bed so i use that time to teach Exchange Server basics to the needy in bahrain. all this extra activity that i have taken on has left me with very little time to continue saving the whales.
As most /.ers should know by now, the Chinese government just ordered all ISPs in China to start monitoring
. ,It is glad , :
email for subversive phrases and the like, so just reply to
Chinese spam with little replies of the form at the end of this spam.
Might be a useful tactic on companies who think that unsolicited
email is "just regular advertising".

Thank you for your coded order. The weapons and ammunition
will ship by way of the usual route in ten days, and you
already know our secret Swiss bank account number to
wire the payment to.
It is a pleasure doing business with you for so long,
and I hope your cause will prevail. I am new to this
particular computer, so I hope the encryption is
working and the monitoring authorities cannot read
what I am sending you.
Long live the Falun Gong! Free Tibet!

I usually have no problem getting replies from foreign ISPs in English. For some reason though, they all seem to keep telling me about some postmaster account being over quota...

The trouble is that every address you use gets on spam lists and gets spammed forever. By having 100's of addresses, you get 100's of times more spam than you otherwise would. Even if you can filter it on arrival so you don't have to see it, it's still clogging your bandwidth and you can always filter a legitimate email.
Hmm, what about this?
Run your own DNS and mail servers, and use your own domain name. Generate a unique hostname every time you need an e-mail address, and use yourname@00001.yourdomain.com as the address. After you're done with that e-mail address, delete the hostname from the DNS, or change it to resolve to 127.0.0.1 or something. You might still get DNS queries, but that shouldn't take much bandwidth at all, especially since DNS is cached.

in my job, I have had the pleasure of talking to many a customer who had an open relay. Here are some VERY common reasons:
You missed my favourite:
