Many of the Spam messages I receive are sent from DSL accounts with

we glue permissions to IP addresses and omit the time factor).
but is this really the problem?
Believe me, it is. About a year ago, some Spammers were sending
millions of mails around the world and used random addresses from
my domain as sender addresses. I received tons of complaints and
cursing threats from people who received Spam, but didn't want to
believe that I don't have anything to do with it.
Most spam-mails with wrong sender
use domains like hotmail or other great freemailers. And this
freemailers doesn't use dynamic IPs. A test on this domains will
reject much more than 50% of spam...
Yeah, but once you start blocking splam from @hotmail, they will
start to use any random domain.
