Where the spam comes from

Recently I found that some e-mail from Russia doesn't reach my Verizon e-mail account. From other sources I heard that Verizon blocks e-mail coming from certain countries because a large ammount of spam originates there. Or so Verizon thinks. To test their assumptions I conducted a small experiment. I collected statistics for the country of origin of spam e-mail for my Hotmail account. Of course I didn't take my Verizon account because the statistics would be skewed. So here are the results:

USA	27	57%
Korea	5	11%
China	4	9%
Hong Kong	2	4%
Canada	2	4%
Thailand	2	4%
Japan	1	2%
Uruguay	1	2%
Wales	1	2%
Qatar	1	2%
Total	47

So now you know. Keep in mind that the result from Hotmail can also be skewed. Hotmail is free to block e-mail too. But I haven't notice it doing anything like that. On the contrary with Verizon it's obvious. And yes, I turned Verizon spam filter off. POP3 and Verizon filter just don't play along.

For spam coming from the USA, the distribution along the major network providers looks like this:

AOL	8	30%
Comcast	4	15%
Qwest	2	7%
Verizon	1	4%
Other	12	44%
