Relay through your upstream (hierarchical approach)? i.e. Register your server(s) with your provider, who is presumably trusted (registered with the global system).
This is the approach I recommend, and have recommended for years.
A bit of an aside: I recall AT&T Canada blocked all SMTP from exiting their network (excepting their own servers, of course) a few years back in response to a large spam.
AOL does the same. They have a transparent SMTP proxy for all outgoing connections. They've also explicitly asked to have this machine added to certain blacklists, so that people who don't want to receive what is almost certainly going to be spam can choose to do so. If you want to send "real" e-mail using AOL, then use the mail client provided by AOL.
