"The results show that fewer than 1% of mail servers that are named in
mail addresses allowed relaying in August 2002, a very sharp reduction
from over 6% from a year and a half earlier. In the same 18 months, the
amount of spam a typical Internet users receives has gone up
significantly. This shows that the amount of spam is not related to the
number of open relays available."
I'd like to buck the trend for this list and admit my ignorance: if open
relays have gone down in number but spam has increased hugely, how is spam
now being sent, statistically speaking? Illegal hacking of buggy OSs? Or
are the remaining open relays just taking more and more traffic?
I believe Barry (from The World ISP) has mentioned that most spam now is
either being sent via off-shore servers and hacked/virus-infected machines.
