And, of course, that's where things such as SPF or MS's CallerID will
help...
===============
as i understand it... these types of systems will not protect against a
customer of (let's pick on msn.net) msn.net gets a virus and their zombied
computer starts churning out spam... as long as it claims to be "From"
msn.net, then domain keys, SPF, and callerID will consider the message
good. not to mention some spamhouse that sends "marketing email" through
their own server, with their own valid SPF record, public key, etc. for
$5-10 they can even register a new domain for every mail campaign.
interestingly, it would seem that those types of systems would actually
help *me*... i run smasher.org and there are very few accounts on that
server (no one running windoze has an account)... so, if i created an SPF
record for that domain, then it becomes damn-near impossible for anyone to
spoof my domain as a "from" address...

illegal in 1986, no elected official voted on that. It was
done "in house." People are now in jail because they did
something that an administrator declared was wrong."
