As I keep saying, I agree that plenty of spam has forged sources.
The question is whether that "plenty" is 1%, 10%, 50%, or 99%. As I
said, my guess is ~10%. Note that I used the word "guess." I wish
that everyone else who is guessing would admit as much. As far as I
can tell, everyone is guessing.
We filter spam based solely on forged headers and private blacklists
plus user preferences. The number of those messages that have
something faked is well over 50%. We aren't currently logging all
the triggers on every spam message, so I can't give you exact
numbers. But it certainly was the case last fall. Remember though
that there are lots of headers can you can badly fake in a
message--not just the routing ones. We're looking at the entire set
of headers.
As another data point. 16% of the 100 million messages somewhere.com
bounced last year were bounced because they had return-path's that
didn't pass basic validation (e.g. no MX, invalid domain...). That's
before anything even *got* to the spam filters.
Now I will grant that it's possible that the guy who sent email from
Russia through a server in Italy in order to spam me in the United
States actually *did* have a Hotmail account at the time the first
message was sent. I don't know why he would have bothered, but it's
possible.
Can you explain why you think that person would have set up an
account just so that it could get shut down immediately? And why you
think this matters?

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
